Having fun trumps all.

i could care less about my KD but i want to win more more then anything else, but i hate going negative if that makes sense. because of lag ofcourse

Others will want you to have a good W/L.

You yourself will want to have a good K/D.

To me K/D is definately more important. I could care less whether I win or lose in CoD games.

The only game that winning felt really important to me was dead space 2 multiplayer. That game actually had some of the most teamwork based gameplay of any game I played. Even if your were an MLG pro, if your teammates sucked you will NOT do good in that game.
