I've noticed that the new match-maker will unbalance certain parts of the game in was the (very well intentioned) devs may not have seen. Such as bringing a spotter mech for the team. You launch a small spotter mech and the math-maker sees "small" and puts you in a match with a bunch of other "small" spotters. That's one of the fun parts of the game that the (very well intentioned) match-maker will kind of squash, since it forces everyone to be too much the same.
Maybe in our game mode parameters we could have a check-mark option to opt-in or out of the match-maker service.
Or something...
