I agree that Sakura should be the one in place of Hinata in 615. It has always been this way. But, we need to remember that what else could Kishi do in order to develop her character ? Not to mention, he had to kill Neji in order for Hinata to get her spotlight.
He could do another scene ? But what is it ? Her character revolves around Naruto which is something bad need to happen to Naruto in that way in 615, in order for her to step in and her major character development in the manga to happen.
As for Sakura, she won't just sit back there watching the action or just heals some fodder ninja !!! Even if she's a medical ninja that should not fight in the front line, she'll get to do something more than that. Imagine that all of a sudden, it switches to her healing someone and saying few words and that it for her in this war, then switch back to something else 0_o... This can't happen. Never in my life I saw something like that happening to a heroine either. If Kishi didn't show her at all, than he's either messing with us, or letting her shine in the Naruto vs Sasuke battle, or he doesn't know what he's doing which I don't think so cause the man knows what he's doing for his own manga.
