For noob sake. They can't hide. It's so easy to spot a bad player in pvp because theyre always worgen or male draenei. You go attack them and its instant backpeddle/run away/racial/keyboard turn. I have seen a few worgen who werent terrible but im pretty sure 100% of male draenei are bad. If anything give alliance a new race next exp with good pvp racials so they will get played by good players. We have never gotten anything that was actually badass looking so only noobs flock to the nearest looking thing. Worgen and male draenei are a bad attempt.
