Deidara need to be changed, those spiders spam even to 100 of them, and each of them push u far far away, there is no way to hit Deidara like that u cant even use skill y_y.
Maito Gai look like Rock lee but problem is with his 100 lvl gate...it should be deleted for other skill there is no sense in having 2x same skill what give same thing...
And about that secret in game, it was about those generators near village in middle ? i dont see sense in that, some monsters spawn and give nothing...
