Can't do it. Streamers get more subs if their viewers think they are really good at the games they stream. A matchmaking system that's designed like our current, which ensures that they and their teams have the advantage every match, is perfect for streaming. If streamers and their teams were constantly having to fight other teams, viewers might realize that they actually kind of suck when their opponents can fight back. That would mean less subs for the streamers and less free advertising for Bungie. :P
