Seeing as how Blizzard is making male and female warlock pets I thought it would be a cool idea if they added new race skins for/from the expansions.
It could be something like if you lvl a dwarf to 80(wrath cap) you would unlock frostborne skins for your dwarf characters. Or maybe just get any character to 80.
Burning crusade race skins could be Broken, Mag'har, Fel Orc, Sand Gnome, Wretched
Wrath skins could be Darkfallen,High Elves,Ice Trolls, Taunka,Vykrul, Frostborne,mechagnome
Cata skins, Dragonmaw, Wildhammer,
