Some things to say.
Outlands is a VERY small portion of what Draenor used to be. If Draenor is similar to Azeroth, then the Outland is smaller then one of the various continents- and Draenor probably never experienced a sundering before the opening of the portals. So yea. The Outland is part of Draenor. The Outland is NOT all of Draenor. I think that we will most likely go to an unbroken part of the planet to do... various things. Mostly kill things and collect lewtz.
