If you were worried about min/max for race, you'd be troll this tier. Like others have said, pick something you think looks fun. There's so much RNG in dps these days, it's not going to matter. Frankly I love draenei cast animations on my shaman, my worgen lock is just weird looking, lol. My mage is human. It was my bank alt and I decided to level/gear her for raiding back in Cata.
