Pretty fail outlook at it. You must be just bad.
If you CANT kill somebody with a jetpack then you either have your TV off...or you just cant aim. Energy sword, hardly ever on the map and game mode you play. camp in spawn? I havnt seen that, Ive seen campers but as for camp in spawn...its not even smart cuz you spawn in semi-open areas. Same maps? you obviously just watched videos on it because if you have played it you would know that there are only a couple remake maps.
The reason why you dont like the game is because it requires skill to play it, something most people like you fail to attain and understand. So back to being "pro" at MW2 and leave the real people with skill to their own domain.
