So, basically, the explanation for WoD is that Warcraft now has multiple universes. So, I get that we're going to "Draenor B" and not our Outland... But... Why did the Iron Horde even have to come to our "Azeroth A" when they could go to their own current version of Azeroth, which would get Garrosh out of our hair, and he could conquer a world with... A lot less defending it. I mean, think about it, before Goblins started getting big, before Orgrimmar was fortified, before Orgrimmar was FOUNDED.... Wouldn't it be a hell of a lot easier to create a new world for the Iron Horde in the alternate universe? Hell, maybe they would stand a chance against the Burning Legion. Good on 'em. Why come back? Um.
