The Carrier is in. We brought it back for several reasons. The biggest reason was that it was currently the only unit still removed from the expansion. Back when I had this crazy plan that we would "cut units and add new ones" we cut a bunch of units.
Over time this plan did not work out. Cut units worked there way back into the mix and finally the only unit that was still cut was the Carrier. It seems weird to cut only one unit from one race. So it's back in. And it's staying. We should have put it back before the beta started but we didn't and the community reminded us how important this was

Also apparently through rumours on the Pro Forum Dayvie has said that they're looking into the nony changes , but would rather focus on HotS units..

Could this expansion be renamed Heart of the Carrier? I hope so!~
