Remember Naruto asking Jiraiya and Kakashi if they were going to teach him a new ninjutsu?
They told Naruto that the Rasengan was the ultimate shape manipulation jutsu made by the 4th Hokage, and compared to that, no other jutsu matters....
Jiraiya trained Naruto to be able to use rasengan whenever he wants. Kakashi has a limit on the number of Chidori's he can use... Naruto does not seem to have an end to the number of rasengans... THAT is a feat in itself!
Naruto didn't train to become faster, or smarter... just on expanding his chakra capacity. This also will help him to avoid using the 9-Tails. I think the idea is to make Naruto the dominant figure, vs. the 9-Tails thinking its dominant. Only way to do that is to make Naruto's chakra a lot higher.
