Noobtubing is one of the things that really kill the game. It's so easy that you can literally shoot it in the air and get 2+ kills.
As for the camper arguement, it's not really that hard to take one out. I'm an excellent CoD sniper, so they aren't a problem. I also don't believe camping is something that ruins the game. In fact, I myself often camp. Why? Because it's the reason that camouflage exists. If I'm not in somekind of a secure-ish location with a sniper rifle, then wouldn't I just be quickscoping?
If you don't like ARs , MGs, SRs, or LMGs, maybe you should try the good ol' shotgun.
