The ppl with the highest k/d's are the ppl who sit in the back of the map and snipe or who use their sniper as a primary. That playstyle is going to lend to a higher k/d but if you're more of a run and gunner, you're gonna have more deaths. Me personally, I'd rather have a game with 20 kills and 20 deaths rather than sit in the back of the map and g0 10-2.
