We are not interesting to get redeem to the alliance player eyes because i currently feel bad about playing my own faction and having the alliance player accepting the horde faction won’t make me feel better about playing it.
WoW is a game about faction rivalry. While we don’t need to get at war with each other every few expansion, we also don’t need to love each other. Alliance player shouldn’t need my appreciation of the alliance to feel proud about playing the alliance and horde player also shouldn’t need your appreciation of the horde to feel proud to play horde.
So it is just 100% natural that horde player seek a way for the devs to redeem the horde to the horde player eyes. No need the alliance acceptance for it.
