We have a couple of kekkei genkai, y not add the others, we should be able t have all of them in the game.
Boil Release:Fire & Water
Dust Release:Wind & Fire
Explosive Release:Earth, made for lightning Chakra type
Lava Release:Fire & Earth
Storm Release:Lightning & Water
Wood Release:Earth & Water
Scorch Release:Fire & Wind
Magnet Release:Wind & Earth
None of these would effect the game but i think it would be good to have all Kekkei Genkais
