In halo 4 though this is unlikely i would like to see a 2v2 and 4v4 series based playlist !!
For example instead of playing one doubles match and losing to people who camp with shotguns , you play a series of three games , a slayer , a oddball , and a one flag gameptype, this would improve team-based gameplay, allow players to redeem themselves after losing games, and shape a more competitive community ! Let me know how you think this would work in matchmaking !
So you want games that have multiple rounds?
