Hybrid sucks.
Hybridization is the worst thing in the game, because of this classes have lost their individuality for the sake of players who want to play on one class all the roles, etc. And what in the end? Hybridization is an unfinished piece of a big joke that has no future. Don't ruin races with the same thing.
Those races are a little hard to hybridize without breaking the lore or overtuning them, although I wouldnt complain a power boost to my Bretons :P Personally I like them making hybrids more vialbe although I think they are a bit too enthusiastic about that. Some set could also stay pure.
