Awesome... :oI really like the idea of having 2 VS 2 , 3 VS 3 battles etc. This could also add a lot more achievements to PvP. Thinks about something like:
Try to kill all the players in a 3 VS 3 battle
Try to win a 2 VS 2 within 1 minute
Win a match of 2 VS 2 with your teammate being dead
Win a 3 VS 3 with all your teammates being alive.
