Black Ops K/D was a 3.3, but that was only after playing for a hell of a long time until I mastered the maps on a second account.
I think a lot of it is the people playing right now are of about the same skill level and nobody really knows the maps, so you aren't going to see a lot of dominating performances like you may be used to.
Just give it time, you'll get used to the game and whatnot. I'm sitting at 1.6 but it's steadily rising.
