I imagined different races doing the Cannibalize and changed my mind about all racials being binded like in original game, maybe a better option would be leaving the insignificant ones like this & underwater breathing, profession/weapon bonuses and other minor passive&active abilities to their races (for example Cannibalize, humans Diplomacy, NEs Wisp Spirit, maybe gnomes intellect, trolls beasts damage etc). Then it'd be even easier to rename&restyle assumed "Birth Signs" so they could fit in Lore, and races would still have unique abilities that don't ruin everything.
It's important to try to predict how people'll minmax combining racials when deciding which should stay with races, to prevent people from choosing one faction over another (bc of minmax) again. Though I hope with EMFH & other prime abilities being accessible to anyone, the minmax won't be huge enough to affect factions.
