Naruto being weak at the start of part 2. Also creates mess. When Naruto can master stuff, that it takes years and years (and not even completing it even then) for others to master it. Yet naruto does it in week/s.
At the start of part 2. Naruto should have had more speed, agility, one hand rasengan. Some wind jutsy, understanding of elemental training, and already started to learn sm.
It would have been more fluid. And it will not make it asspull!
Seriosly. Jiraiya didn't even test Naruto's afinity. It's like he was. You don't need to be strong yourself, as long as you can use Kurama chakra that makes you op. I read a fanfic recently. Where Naruto questions exatly this. While he is ok with training for Kurama's chakra usage. He didn't want to depand on it. And want it to become strong on his own. With Kurama only to be used as the last resort.
It's sad that normal people on fanfiction have more understanding of Narutoverse that Kishi never had!
And as I keep ranting at times, that's exactly one of the biggest problems with part two (Naruto being so weak and apparently barely doing anything with Jiraiya), and it also shows how it seems like almost all of Naruto's "senseis" that he's had have...well..not been very good.
As Naruto thought of with Sasuke, Iruka was much more of a brother than a sensei, so while not a "bad" sensei, he didn't really actually teach Naruto much that we've seen.
Kakashi barely taught him jack aside from the "secret" of the Kage Bunshin (which you'd think even someone as dim as Naruto would have noticed LONG ago considering just how freaking much he used it AND with the number he would make) and the very basics of elemental training (which, again, Jiraiya should have already done)
Jiraiya, if the Summoning and Rasengan training were any indication, has shown to be the type of sensei to simply teach the basics, then just leaves the student(s) to figure out the rest themselves, and if that doesn't work, throw them into an extreme situation (literally, in Naruto's case) to force them to get it done or die. He was also probably spoiled a bit as a sensei due to Minato being such a "genius" at Naruto's age, so he probably never had to be that attentive to Minato, who probably understood and got things done relatively quickly.
You'd think that, after the horribly failed attempt at releasing more of Kurama's chakra that nearly got him killed, Jiraiya would have actually gotten serious in training Naruto in much more practical things. Heck, you'd think that he would have been smart enough to see that only releasing more of Kurama's chakra would not have done nearly as much as he thought considering the group he was supposed to be preparing Naruto to face were all S-Rank shinobi specifically chosen for being useful against Biju/Jinchuriki, even if they could control the chakra (Itachi and Kisame being perfect for countering Naruto with Kurama thanks to the Mangekyo Sharingan and Samehada). And even then, Naruto would have gotten easily owned by a shapeshift clone of Itachi with, at max, only 30% of the real Itachi's power were it not for Kakashi and Sakura being there, and even then, they barely won. That should have been a huge wake-up call.
Ironically, the only good sensei Naruto had was Fukasaku, a Summon, because he actually paid close and serious attention to Naruto's Sage Mode training. If it had been Jiraiya, Naruto would be a toad statue right now (though that would probably be a preferable fate in hindsight, lol).
