Id either do +nin -attack or +life -attack depending on what you want to use him for.
I don't see a point to the people doing +attack, it his lowest growth stat so it's pretty much a waste since the boost is % based, which also mean that -attack will take away the least stats too. :lol

yup u are right but saw too many ppl doing +att still didnt get why they go for it
most of his skills are also nin :o:o:o

Most of his skills not nin, but tai\nin. Which mean that you need to raise nin and tai both. Better nin.

but u see his skills are tai/nin or nin only
thx alot for your answer
but u saw top players using him +att?

You see, you need to raise or nin or tai - both will be good. Which one better depends on Naruto stats. Without any equipment - nin is better. But most likely those tops have much higher tai.

hmm how do they get higher tai??

With equipment of course. You see if tai (not starter tai, but overall on char) is higher then nin, it's more logical for THEM to raise tai. Even if raising nin will give more stats. But there is almost no difference beatween tai and nin. 100-150 points.

just my 2 cents, since Naruto's life growth is highest, and i think one of the highest among all ninjas, no point boosting it further. u can have other ninjas giving him shield and he has clones in front of him most of the time. u can boost his life through other methods like magatamas.

so that's why many players boost atk or nin in the mood.

what is the best mood for sage naruto?
