K/D is dumb. I don't even have 1.0 (close but no cigar) but I'm consistently at the top of the chart in most games. Meanwhile people with really big K/Ds usually do nothing in the game. I finished a control match at was stunned when I saw a guy on my team with a 6.0 K/D. I thought that was amazing until I realized that he had 6 kills, no death and no captures. Which means he basically hid the whole game.
