I've always been a melee fighter, bith in game and IRL. So warriors, hunters and rogues are always my preference. Warriors, however, have a special place in my heart. Granted Warriors don't have the Int or Wis of the spellweaver classes, but who needs it.
Races, Since BC is Draenei. They remind me a lot of me, I just feel compelled to roll 'em. Second, Night Elves. Dunno why, they just draw me in as well.
With Cataclysm coming out, I think it's very clear where I'm going with this. I've written so much a lycanthrops (I hate the term "Lycan", it's contrived and overused) I am running with a worgen and might trump out my Draenei Warrior.
