Granted i've only played MW3 for the frst 2 days, but i thought they'd done pretty well with altering the game play, try playing in "Support" role, its totally different to any COD before it. Granted they need to sort out the weapon damage business, which they no doubt will as they did it on black ops and got it pretty much spot on eventually. The main issue with it is silencers, put one on your gun and it becomes about as effective medium/long range as a one legged man in a arse kicking contest. Close range they're still alright. Other than that, i found it too be the people who were playing the game to be the greatest annoyance, too many clans playing objective modes (Headies, Dommintion) etc meaning you cant join a game with randoms as you just get raped, and too many people worrying about they're KD and camping with Blind Eye/Assassin on. I use both these perks but spend about 80% of my time in the enemies side of the map capturing they're flag and defending B flag so it helps for me to not come up on their map.
