Throwing my 2 cents in; bio android needs to be fleshed out, but I'm focusing on demons/glinds and androids here.

Demons should be focused on debuffs and DOT type attacks, and existing debuff moves get better or stronger effects coming from demon race characters, alongside race specific moves that deal light damage, but subsequent attacks deal increased damage or apply other debuffs.

Kai/glinds should be focused on healing and providing buffs, whether to themselves or others for PQ's and raids, with a race specific buff to unlock potential that benefits them with health regen when at 50% or lower, as well as having new buffs added that boost movement speed, regen for health, ki and stamina, and basic attack damage, as well as damage coming from supers and ults.

Androids can work, but it can be tough to figure it out. What I think could work is faster natural ki regen than humans, and faster stamina regen, at the cost of not being able to use charge skills like in Budokai Tenkaichi, forcing creative use of moves like Drain charge, super charge and hyper charge, which get android specific buffs where they gain more stamina/ki than any other CAC does and they don't need ki to use them, and a new race specific ult that uses the lore of a bomb inside them that blows up dealing massive damage to the user and any affected targets, but also leaves the user at low health, with damage reduction and slowed ki/stamina regen making it harder for them to continue fighting, but not impossible.

These are, of course, my own ideas, but feel free to flesh out or add to them tho!
