Hey its that guy with the funny sig. lol. Anyway you proved my point when you said critical moments. The most important fights he ever had (not all of them but most) he used ninetail chakra. Shall we do a list of defining moments when he has had to use it.people always think that naruto took kurama's chakra for granted and always helped him,yet the problem is kurama's chakra only helped naruto in critical moments only,and when naruto tries to train for something new,kurama is no longer helpful,matter of fact it was a hidrance to his skills until now.
people only look at the bright side,they never look deep into stuff,such a shallow view of the world is honestly pitiful.
