Naruto handed him chakra after Kakashi fought for two days straight, used four normal Raikiri, two Raikiri through weapons (kunai and cleaver), two Raiden, two shadow clones, five Kamui, and a Doton wall. And those are just the on-panel techniques we saw - its very likely he used even more over the 48 hour period he was fighting where the panels were not focused on him.Didnt Naruto handle him Chakra back there? If he didnt it would have been ridiculous. In the fight against Sasuke Kakashi could barely run after using ONE Kamui. The Ninja war was just some time after that and its almost IMPOSSIBLE for Kakashi to have got that much stronger in such a short period of time with no explanation from Kishimoto. That would be a plot hole.
Its not a plothole at all. Kakashi didn't get stronger, he just adapted to his Mangekyou better. Kakashi has consistently adapted to his eye throughout the manga. At first, he collapsed from base Sharingan after about 10 minutes (vs. Zabuza). Gradually, he was able to keep it active for longer periods of time until he was able to keep it active for an entire day while sparring with Naruto and Sakura. Finally, in this war, he was able to keep it active for two entire days.
With the Sharingan draining him less and less, Kakashi has more chakra available to him to use other jutsu. Kakashi's stamina in the databook is a 3, but look at what both Sasuke and Orochimaru accomplish with similar chakra levels. Kakashi has adapted to the Sharingan to the point he basically has Uchiha-like synchronization with it, thus it leeches him less and makes him look stronger because he can allocate his stamina to things other than maintaining the Sharingan.
It isn't "may be true," it is true, and you know it. You used a ridiculously outdated feat to try and support your argument. It would be the equivalent to me saying Naruto doesn't have Sage Mode because four hundred chapters ago he didn't have Sage Mode. Using Kakashi's first attempt at using Kamui to his detriment is pathetic when we have been presented with a plethora of much better feats, which you choose to ignore. The hilarious part is that even when Kakashi sucked at using Kamui, Deidara still stated that Kakashi had Dojutsu on Itachi's level and he still tore off Deidara's arm off.May be true but Naruto in sage mode was fast enough to dodge the Raikage`s attack, so not only is he very fast in his reactions but in his physical speed too, I think Naruto can escape the Kamui.
Naruto dodged the third Raikage, who is not as fast as the fourth. Obito's Kamui pushed Minato's Hiraishin to its limit. Kakashi's Kamui outsped Obito's at point blank range and left him dumbfounded as to what had happened. Kakashi's Kamui is among the fastest techniques in the manga, and the only technique that is superior to it (speedwise) is Hiraishin. Nobody short of Minato himself, BM Naruto, or the fourth Raikage with maximum Shunshin have any hopes of dodging it with pure speed.
