On CoD4, the first online game I played, my k/d was 0.97. Then in WaW, it was 1.42. Now, in Mw2, it;s 2.05. It all depends on how you play. I hardly ever go for objectives anymore, and play for fun, but I also try to maintain a decent k/d ratio. On the other hand, people who play purely for the objectives will have a lower k/d than those like me.
