Mag'har orcs and other character customizations!
With Grommash now at "peace" with the rest of Draenor, we should be able to "recruit" the brown orcs of alternate Draenor to the Horde. This meaning we can make our Orcs brown-skinned.The Dwarves have made peace with the Iron Dwarves and the council contains both Iron Dwarves, Bronzebeard Dwarves AND Wildhammer Dwarves, so Dwarves should be able to have tattoos or dark skin as a customization. There are more like these, but these were just the ones I could think of. Really think this should be implemented in the game.
