I have to agree about Ten-ten. If this was a realistic show, then sure she'd probably be pretty hardcore... But, at the same time this isn't a realistic show--and to make it even funnier, I think it was Gai who said she never misses her target or something. Lol, seriously using weapons in Naruto (without a catch, no special abilities, no combining your chakra with it etc) seems pretty useless. People deflecting kunai, shuriken, etc.
