ya man I understand what you mean by that, But I think I can pull off a invasion game mode exept with a little different twists. Extraction, and Dominion are the most useful ones to use to pull this off. Dominion at least gives you certain points for what you do, Exraction at least can destroy certain objects such a gates to progress to another level. I don't know yet but I will try to get something as close as possible, maybe I so I will give you a friend request.
