Wheres the proof that shes going to stay back as healer.

A noteworthy emphasis on her medical function, particularly whilst she is in her "current state". Naruto and Sasuke stated their intentions to continue fighting but it's not the situation for Sakura. This is an obvious reference to her seal. If Tsunade's ability to remote heal is any indication, Sakura will only be capable of long range restoration so long as she has chakra remaining in the seal. Why would she consume the remaining quantities that she left just so she could fight the replicas? Despite our yearnings to see a more combat oriented role her main job will always be healing the injuries of teammates. Sakura is the only medic who can reach the shinobi due to her remote healing jutsu and they are being constantly injured by the ever strengthening Jubi replicas. But I have reiterated this numerous times to the other poster.
If theres a reason for kishi to give her the seal then it was for her to able to fight,
She's currently exploiting its benefits for restorative purposes just like Tsunade during the Invasion of Pain arc. Sakura fought for a single chapter and now with the Alliance on the brink of total annihilation she apparently needs to be ready for mass healing.
I can foresee Tobi creating a shockwave similar to the one the Jubi made 9 chapters ago and Sakura, in her efforts to protect everyone, using the remainder of her seal's chakra to protect everyone from the impact. It is after all her duty to protect and/or heal others.
Just now because shes not fighting those 2 (actually 1 chapter where she could)
No, it was two chapters because that is the amount content that she has not made any appearances in. Sasuke wasn't visibly seen in chapter 636, but Naruto was and Sakura has been missing for two. If we refer to the amount of narrative progress that has been made since she last fought the total would equal 5 chapters for her.
doensnt mean that shes not going to in future chapters. Especially now after Obito turned into the main villain and they are going to need every strong fighter to attack.
No, with Tobi being in possession of the most powerful entity of nature and factoring in its aptitude for creating titanic shockwaves with its chakra alone Sakura will feel compelled to protect everyone a la Tsunade with Katsuyu during the Invasion of Pain arc. She is the only medical operative capable of doing so and the only one able that can heal in any efficient capacity inside of the barrier.

If Sakura was going to do anything else it would have occurred after Naruto and Sasuke had failed in their objective of defeating the Jubi and when the they were being surrounded by the replicas. At the moment she is either having to continually restore the injuries that any shinobi sustains or she's still perched atop Katsuyu staring blankly into the carnage.
The only reasonable methods that could allow her to bypass this restriction would be if another equally competent medic appeared to take her place or if Naruto can once again distribute his chakra to everyone. The former would be questionable since Sakura's replacement is a shinobi who would be the more logical choice to have as a combatant. As for the latter, well Naruto is still unable to provide the shrouds nor would he be capable of reaching everyone with the replicas and a newly Juubi empowered Tobi roaming about.
Complaining about her absence for till now one chapter is far to early.[ Somehow reminds me about the complaining of sasuke becoming bad, some chapters later.... well
The difference is that proponents of the theory that Sakura will remain unseen or non combative have legitimacy with the arguments they make when taking into consideration the circumstances of the situation that Sakura and the others are in.
I don't have a proof. I told you that I'm just thinking and saying what logically could she do afterwards from what the story is showing us.
There is no logic to that suggestion though. The expectation is for Sakura to return to fighting, essentially endangering the most valuable restorative asset that the Alliance has, whilst inadvertently condemning the multitudes of shinobi who become injured to death or the inability to protect themselves because of the nature of their wounds.
She's the only one who can heal at the moment. The most effective contribution she can make is to remain able for healing when the request inevitably arises. I despise her passivity. Mass restoration in the background isn't how I would define a heroine but Kishi may be accounting for the practicality of her decision to heal rather than fight.
Plus, to prove that Sakura won't have any further role in this conflict ? Do you think that she'll just sit back all the time watching the show?
For however long her medical expertise will be required in this battle that has been raging for countless hours where thousands have been constantly damaged throughout.
Last time the ability she used from her seal is healing the alliance,
Until she displays any non-supportive talents that the seal offers then healing is its only ability.
and she's the only one inside the barrier that could heal quickly the whole alliance... So that means that she'll be all the time sitting and watching ?
A medic does not endanger themselves by jumping headfirst into conflict. They remain to the side where other shinobi can protect the one asset that can lengthen their survability rate. Yes, she will probably act a healer for the remainder of the fight unless Tsunade assumes her role, Naruto distributes his chakra to everyone once again, Katsuyu decides to heal by herself, or if everyone else is killed which would invalidate her need to remain out of the fighting.
I'm saying how that can't happen for Sakura.
I'm also disputing that she can't forsake her medical duties just to appease some fanbase's inkling for her to battle. It's difficult to admit to but I think choosing to stay back and heal is the best decision she made. Remember that the Alliance is doing in its power to win this fight. Having a medic who can constantly revive others and put them back into the fray is supplementary to that objective.
I'm seeing what she could possibly do in the future. I can't tell you specifically. I'm saying how the events will eventually make her move.
You haven't offered any rational explanations to reinforce this cryptic affirmation of yours that Sakura will eventually come back to Naruto and Sasuke's side. On the other hand, I do believe that I've firmly corroborated my argument; numerous times now to two different people.
The information that you want to know about her techniques, you may know them in the upcoming chapters.
The confidence in a possibility that she will reveal additional skills has been tarnished. At the moment, I don't expect much of anything from her except additional healing. Whatever you or the user may believe is assumption until Kishi provides verification.
You have a point that she have to do more seeing that before she arrived to the battlefield, she was absent many times. But, there's things now other than Sakura.
Generally speaking, whenever there are other characters or situations unrelated to the few plotlines that Sakura retains she tends to fade into obscurity. We witnessed this in the Search for Tsunade arc in P1 and later during P2 she was completely absent for a third of the manga. My apologies if the notion of Kishi consistently casting her aside once again, after doing so just less than twenty chapters ago, offends you.
How you're saying it is like Sakura have to be the center of everything in every event.
No, she wasn't the centre of attention even during the Sasori fight; what is oftentimes considered to be the pinnacle of her development. It was shared amongst Sakura and a new addition to the cast.
Please, don't misinterpret my intentions. Sakura does not and should not receive every single iota of panel time but suggesting that she have an equal amount like her male counterparts whilst not having the semblances of a side-character for 3 major arcs, I believe that's not unreasonable.
Wanting Sakura here and there won't happen. Even the hero of the story isn't in every single action that has each character going through.
Here the difference is that Sakura is not "here and there". She hasn't been of any significant importance or focus for three whole arcs since P2 began. And for the majority of the war she was as pronounced and impactful as Hinata or Neji. Team 10 achieved more at this time and now with this moment being the first time in hundreds of chapters being discarded after a few chapters, you expect any dissidents of this retraction to complacently sit back and accept that she "might" show up again? For what, exactly? More parallels? Romance? This character hasn't had the bearings of a protagonist for much of the main story. And no, I don't address romance subplots or the frequency of her reaction panels as indicators of a heroine.
Cause what Sakura should have to do with Obito in this moment?
What does Gamakichi have to do with Tobi? Why were three fodder shinobi provided with a panel so they could state the obvious? You mean to tell me that Sakura's concern for Naruto and Sasuke as they stage an assault Tobi doesn't warrant a panel but fodder making trivial comments does?
Naruto and Sasuke just got to go to Obito, and just Sasuke landed in front of him so that he'll hear what Obito say to him and whatever concerning Obito that will lead to another thing.
Sasuke's intention was to kill Tobi so Madara's resurrection could be prevented. The statement Tobi made was a product of coincidence since he was already incapacitated by the time Sasuke was standing before him.
Her priority in a fight is being a medic, but when she wants to fights, she does engage like we witnessed few chapters back.
How does this negate the fact that her medical duties take precedence over fighting? Sakura has assumed the role of the group's medic. They're dependent on her for their survival. Unless Sakura chooses to uncharacteristically leave these people for death when they become injured then she'll continue to focus on healing.
Sakura have to show up in every single chapter? Even if she's the heroine, she doesn't have to. It's been just three chapters and possibly another two or so, so it doesn't mean that it's something not right for her.
I have addressed this various times already. Here is the most recent reiteration from a few reponces above.
"Here the difference is that Sakura is not "here and there". She hasn't been of any significant importance or focus for three whole arcs since P2 began.

Kakashi before 636 hasn't been shown for a few chapters back cause it's not set for him to be shown, not to mention that he's not shown in 637 either... It doesn't mean that it's not right for him.
Kakashi had ample reason to appear in chapter 637 but did not. Despite his frequent disappearances from the spotlight his role as Naruto's teacher and as a protagonist has always remained in tact. He displays heroic qualities in a qualitative manner that is able to offset any damages that his absence from one arc may have. Sakura has done nothing but carry out supplemental roles which the innominate healing fodder can carry out. Beyond her status as Tsunade's apprentice, a fact which is scarcely brought forth, and Naruto's love interest, there is nothing that distinguishes her from the generic stick figures littering the battlefield.
You can't honestly say that Kishi has performed adequately with depicting Sakura as a consistent heroine of this story. As I said before, heroism is subjective in context, but what Sakura is doing at the moment has undeniably less impact than the many accomplishments that Naruto, Sasuke, and Kakashi have under their belts. Her participation as the protagonist has been lacklustre and even Kishi's previous statements have attested to this negligence.
So once again, I'm sorry that I would like to see more from the character who is flaunted as being a heroine of equal status to her male colleagues (which chapter 632 was attempting to emphasize).
You want people to believe that she is just as capable or as hero-like as Naruto or Sasuke? Have her do more. Kurama put it best, "prove what you can do with your actions". If you define heroism as obscurely hiding behind others so they heal the insignificant then good for you, but I don't think there is anything wrong with expecting more from this supposed heroine.
