I think this will create huge money for blizzard. Even if its only weight 1,2,3 in the barber shop.
Why? Because some people might re-roll to be a skinny Kul Tiran, a skinny Panda, a Fat Human, a Fat dwarf etc as it will fit with their dream aesthetic. No major reskinning needed, I’ll deal with blurry textures 
then next expansion you can say “upgraded textures”… when you get around to it if you feel you need that.
Skinny panda sounds terrifying. I’m in.
People have been asking for more body proportion options for a long, long time now.
The big issue is that it will only be minor variances, as major changes to body physique will require entirely different rigging (case in point: the skinny human/kul Tiran).
The best example of what we could expect would be current Dracthyr choices.
(Also this belongs in General, not PTR as this is not feedback to anything currently on PTR)
I don’t want to repost it so happy for someone to move it. Also they’ve said in the past they don’t read general posts, and they don’t enough feedback in betas. That was my thought process right or wrong.
