Trolls and Draenei get Druids in cataclysm, night elves get mage, blood elves get warrior, dwarves get shaman, and a bunch of other stuff.
Trolls don't even make sense as druids. They're all voodoo and stuff.
I'm a blood elf on my pvp server. The only thing not to like is some of their jokes and other lines, cuz they're really snobby.
I hate the people who tend to play as Blood Elves. They remind me of the friends that still teabag on FPS.
