Naruto needs higher genjutsu skills.
He can summon the toads and their sound genjutsu is terrific, maybe as bad as tsukuyomi.
Another thing,
I think for the next databook we will get a "Senjutsu" category, where Naruto will completely smash Sasuke.
Senjutsu:
Naruto -5
Sasuke-2.5
Considering what we have seen, Sasuke's greatest senjutsu accomplishment is the fact that he could mix juugo's senjutsu with his Susanoo. besides that, nothing.
Black chidori? Hah. Tell that to Senpo: Yoton Rasenshuriken =D
