I think that you should be able to play the game you want to, which is what MW2 allows you to do. However, I believe that some things need to be fixed. 1887s should not have that kind of range...and damage at that range. The distance on Commando should be shortened a little....you're a guy with a knife, not Strider Hiryu....ever spec a guy from the side killing with Commando? They slide forward without moving about 3 to 5 feet. I don't know how bad the cheating situation is to you, but I would still like to be able to play on a server where they can get kicked, same thing with people constantly yelling and babbling into their mics pre-game.
It's the usual bitch and whine fest I know, and I do enjoy the game despite only being average, but I've only logged about 15 hours into the game and stuff is grating on me big time. Please no "Learn to play better, noob!" comments. I never want to be THAT good at a video game. It's casual for me all the way. I prefer to win at life.
