I have a 200SPM and 1.48 K/D on HCTDM and that is all I primarily play. Like u as far as K/d is concerned I am usually at the top of the leaderboard, but it goes by SPM and I get beat there, which I really have never understood. I usually get anywhere from 20 to 15 kills a game with under 10 deaths and seems my score per minute never moves.
I run at a slowly climbing 1.36 kd and 216 SPM, but I only play HC TDM and screw myself over by running a pistol-only class on maps like Hijacked or Plaza. That'll destroy your KD!
My friends tend to be in the 1.5-2.20 KD range and we're usually all the top of the lobby leaderboard when we play.
And, contrary to popular belief, if I get trashed in a game by someone who's genuinely good, I'll drop them a note to congratulate them.
