Meh, my KD is at 1.83 right now. I didn't start trying to pull my KD up until I hit level 50, and by that time I was 3300K/3000D or something like that. I got up to 1.90 (maybe 1.91 not sure) and then gave up, got annoying playing like a try hard all night just to raise my KD 0.02 LOL I'm sure if I tried from the very beginning, I would be at a 3.0 KD but I can't be bothered...the game just isnt as much fun when you focus too much on your KD.
I'm more interested in zombies anyways. I play Black Ops on PS3...hit me up if you wanna play zombies (and you're not a complete idiot that doesn't understand basic strategy =p)
EDIT: I'm an idiot, just realized this was the 360 forum, I'm running on an hour's sleep...LOL
