I have a feeling this was probably asked before, but... what if WoW offered racial skins of minor races in the game? Purely cosmetic mind you, a much better alternative I think to making yet another race to level as. It could be something you could do at the barber, or maybe even character creation. Hell, some of the alternatives I'm about to offer I'd even pay real money for!
Dwarf: Dark Iron, Frost, Iron and Wildhammer (tatoo'd heavily)
Nelf: Highborne
Gnome: Leper Gnome, Jungle Gnome (like so many procs and items, could be a fun joke)
Draenei: Eredar
Human: I'd say differential on 'actual' human races but I'd fear the controversy our 'enlightened' community would pose.
Worgen: Classic old worgen? Oh wait, better, it uses the existing worgen model: Saurok.
Pandaren: Here's where I have some fun... Furbolg!
Orc: Fel Orc (red) and Dragonmaw (greyish) and Mag'Har (brown)
Tauren: Yaungol, Taunka, Grimtotem (black skins with white skull face paint/tatoos)
Troll: Zandalari, Amani, Drakari
Forsaken: hmm, not sure... wait! Skeletons!, the wretched (magic addicted belf, uses same base model)
Belf: Highborne again, San'Layn (belf vampires from ICC. Naxxanar was merely a setback!) Demonic Belfs from Sunwell...
Goblin: Classic pre-cata gobbys, Gilblins
Unlocking these could be a store thing, and achievement thing (like maybe obscure factions such as Hydraxian Water Lords for Dark Iron, etc) or even just plain free. Opinions, please? (double edit, I keep forgetting belfs.)
