MW3 (Slight letdown)

I have been playing MW3 since about Christmas and it has been a slight let down the levels until you get the PPM901 are complete agony. after that leveling up is really easy but even past that hard part there are still problems like a glitch that I use to play dead all you do is go prone and press Y really fast it helps to not have slight of hand, and beyond that noob guns rule the game, guns like the MP7 and Striker dominate the game. I get decent scores like 20-8 and at least four deaths are by the MP7 or a shotgun. Now currently I'm level 80, and trying to get all of the guns to level 30 or fall camo currently I'm on the FAD which is level 27 and  once I get it to level 29 it will go  to 30 so it will be fall after that then I'll be using SMG's. Which will go by fast considering the SMG's as I have already stated dominate the game.
