I agree with Michael church, approximately 7 out of 10 games I've had people leave on my team or the other team. It's absolutely brutal, the games take forever and it isn't fair. start removing REQ points or removing rank. I don't know what the solution is, but this is definitely a problem. Please 343, address this issue, there are way too many people leaving Halo 5 games in matchmaking and the most severe punishment seems to being suffered by the players who are following the rules and staying in the game.
