3kd, 2.1 w/l, 450 spm here...
K/D could be better but I seem to find myself on the objective more than I should (given my slaying ability). What can I say... The win is always priority.
Play the game to enjoy it I had a 2 w/l ratio and 2.5kd playing solo, and most of those losses were from joining late games or host dashing etc. However I've given up on w/l because playing solo for the win is to aggrevating so if I join a game and it has already started or certain maps like drone,express I just leave because I really don't like those maps or do I want to waste my time. I enjoy getting as many kills as possible and have increased my spm to over 500.
This game is a connection based scam and w/l is ruined by late join BS and lag. Top it all of by not giving people a medal for camping to devalue their crap stats and you got the most arrogant community on earth.
KD doesn't really prove anything , that just shows how good you can camp for high streaks but I would say the W/L is more important then KD... That's my opinion
