Why didnt naruto learn more?

[Strata Uchiha]

You know good and well Jiraiya would of introduced Naruto to Mount Myoboku eventually so that he can start learning Senjutsu. Those 6 Paths of Pain killed him before he could pass down the tech.

Anywho....Naruto has multiple teachers that have assisted a little in his training.

Killer B
Jiraiya
Asuma
Pa Frog
Kakashi
Heck even Ebisu.
