Good. Now remove grenades, fix certain perk combos, change the "laser bullet" bull shit, get a health system that isn't crap, fix spawns or make spawn killing less appealing, make the killcam not pointless bullshit, give the option to choose a set criteria for a match, allow yourself to host a match of a certain criteria for the public, only let certain maps be used in modes that make sense or are generally accepted as fitting for that mode, make the maps good, make the multiplayer actually fun, have the co-op be something worth playing, make singleplayer make sense, and just make the multiplayer more like TF2 in general, THEN I would enjoy MW2.
