How do y'all feel about free cosmetic only customisation? Literally just changing how an ability looks purely for aesthetic rather than keeping it canon?
Example being something like Atavistic Flames, making it Atavistic Water, Lightning, Wind etc. Making it more authentic to the users bio. Something like, "i was raised in water islands so my inner will is fluid like water". And all it changes is just instead of having flames, its water looking instead. Doesn't change the techniques or abilities or interactions. For the sake of the gameplay, its still Atavistic fire, but to match a bio that is all about water, they use that instead.
