As in the sort you find in Battefield. In Dominion mode, I'd like to break through castle walls and join an assault on the castle itself. It could be another point control, or maybe you need to kill X number of enemy heroes before they kill Y number of your basic soldiers. From there, you move to the castle innards. Your objective there is to take the main hall/throne room in a king-of-the-hill style battle royale.

Honestly, I feel like this is already something in the works, just not featured in the alpha. The end of each battle is a perfect setup for round 2 and possibly 3.
