So with blizzcon being only about a month away and the reveal of next expansion being highly likely.
What playable race wouldn't you want?
Personally i don't want ethereal i think it would be unlogical (you wouldn't see them in gear, they are just shadow in wraps)
BTW I'm talking about actual possibilities, so don't say "omg i want a crab to be playable"
No one wants to be a crab or a lobster warlock or something
