waterbomb jutsu needs no improvement, actually, it needs a nerf. The 100 chakra absorb is not needed at all, the mystery is already op enough, you don't need to absorb ALL chakra from your enemy... It gives your opponent no chance to counter you and all he can do is stand there looking at you spamming your mystery every turn without the possibility of fighting back... I used this during bonds yesterday with my friend and so many people just closed the game because they had no chance! they couldn't do anything! The game shouldn't allow this to happen
