Truth be told, k/d doesn't count for much. Mine is something around 1.7 but I care more about my win/loss which is like 1.6 or so. When I run with my friends though and we have a full party though we rarely lose a game.
If I reset my stats i would easily have a 2.0 K/D but I don't want to lose all my gold guns and things. I ruined it at the beginning running around and doing nothing but planting bombs in demolition and messing around with riot shields.
