best bet is to get a bunch of mates on! then your in a big enough team its not so bad
or just play some more
have to admit that MW2 is pretty appauling for matching people, it does do it though, you can tell if you join a noob friends game, its far too easy to win as they have been matched to lower ranked players. if my mate whos a low rank joins me he gets annihilated. speaking of xbox here
