I wonder if anyone would still play default orcs after unhunched superior mag'har become availible. I mean, there's literally no reason to play for an old orc model. Mag'har basically provide all the same visual options PLUS better unhunched posture and additional hairstyles/beards/skins. So I guess we will see default orcs die off slowly, as no one will play them. Would you?
Same situation, but to a lesser extent is with darkspear and zandalari trolls.
All other allied races seem to provide an alternative, rather than superiorly better option for their default races.
