Im on server 1 too and i actually dont wanna help you XD but try hashirama / Iruka / Wind main with 100% more attck passiv and naruto 3 star. You basiclly play with no combos but your naruto should one hit an entire team if you manage too put out the barrier first round.
100%+30%+30%+40% = 200 % more attack and ninjutsu = Rasenshuriken = all dead.

well if they focus hashirma its fine rasenshuriken still wrecks min. half oh the hp of your enemy you still have 160% more attack and ninj.
Hashi is too ez too counter.
