android 21- I agree that ki part is a bit op but i think a percentage increase after a
certain amount of time should still be relevant, like how Picillo gets to a point in his power were he can regeneration his whole body as long as his head is intact rather than getting kill by a getting a hole blasted through his body. With the whole water thing I mean that loosing hunger should be a thing Namekains shouldn’t have to deal with since they don’t eat.
goldfreeza- Well mastery starts in the cell saga so i think that if it should be a trainable thing after a certain point in the story that would be good. Also Frieza is never is beaten out of a transformation like Goku, even when he is cut in half he is still in his final form at full power so I feel that he can just maintain the transformation indefinitely unlike Sayians. So a mastery of a form should be something we can have but we need to make players really work for it, i feel like it would tie in great and would make pvp more dynamic.
