well having invested about 2 hours into the game and now I'm level 8 and it's starting to get fun. It helps that I can play cooler modes now with more players. Had some intense 18 man team death match and domination matches, and I'm having fun messing around with custom classes. I agree the M16 is definately pretty awesome and that's my standard now, along with my newly earned red dot sight. It takes some time and frustration but once you start getting into it, it does become alot of fun.
Though as a side note, I really really hate kids playing this game with voicechat. I don't know how many times I've heard little kids, clearly not even pubescent ones screaming profanity like a sailor and making fart noises into their microphones.
You can find me on facebook as Markus Van Rijn, if you friend me just mention you're from VGchartz and who you are here.
