Every time a game starts I show a 4 v 4 game, but by the end its 4 v 3 or 4 v 2.
Not necessarily a game problem. A lot of quitters exist in Halo. I have heard of some issues with people disconnecting from games. But not a single time that I have played with my group of friends has there ever been a disconnect, so I’m not sure what to believe here.
