Everybody's talking about orcs getting spinal surgery at the barber shop, and trolls at least getting a sub race that don't slouch...
We've even heard from devs in interviews with little "jokes" about undead getting to stand up straight and tall...
While I'm over here wondering if my favorite race will ever not be (total) hunchbacks, and instead get to look this bad-ass:
(this has probably been brought up before, many times, but who can keep track?)
(Yes, I know that's Baine, and he's getting a unique model)
Let's face it, a lot of people refuse to play Tauren specifically because of the hunch, and because it's pretty hard to find a decent looking t-mog for the helm slot.
It's also damn near impossible to really see tabard, chest, or shirt items on the tauren model, depending on braids and whatnot.
