I finally finished my FMJ unlocks for everything and went back to making some classes with weapons I actually enjoy using and, man, it's ridiculous what a difference it makes!
Yesterday, while trying to level up say the M240, I'd go 22-20 in every game. Today I went 65-9 in one using a good old silenced TAR, almost got two EMP's. Went back to silenced SCAR and UMP as well. It feels good to be home!
Also tried CoD Classic (the remake on XBLA) today - why is there peeking out from corners in that but not in MW2?
