It would especially benefit Rping.
You could create an Orc, who originated on AU Draenor, and chooses to join the Horde, or even play a ex-Iron Horde member. Of course for those who want to RP a Mag'har (non-corrupted Orcs from Original Draenor), this would give them that option.
Though if brown skin becomes a reality for character creation/customization, I believe other races should get more variation as well.
