Here are my thoughts on it. First of all you would need a to be a high level to gain entrance (say 32, which is two levels below the max.) Then you match with players who have the same record as you do, and against players who have the same record as you do. (Give or take some for the people who have crazy good records and wouldn't be able to find a team otherwise, and for pre-made fire teams with different records they would be averaged out amongst the group.) This way the games become more and more competitive as time goes on. If you are 3-0, you can be reasonably sure your team isn't going to be horrible, and you are going to have to fight tooth and nail in order to win the game. If you are 0-2 you will be playing with people who are more of your skill level, so once again the match is going to be more competitive. There could even be a party up option like in Halo if you decide that you really liked your team. You could obviously opt out and create your own fireteam if you wanted to, but this way everyone else gets a quick and easy way to have competitive matches.
