K/D is the only thing relevant to you and me. It's the only testament to your skills. Why? No matter if you're thrown into a losing game (17000-9000) you can still play well (aka kill more than you die). But, chances are extremely slim that you'll be able to turn the game around and win. Slaughter house rules can, in theory, send you into losing games all day every day. Win/Loss ratio is relevant when you compare odds against other teams in competitive environments: 1) Destiny is not a competitive game 2) If you need a full team in causal pvp- you're beyond shit Also: you have less than 2k kills with Necrocasm- in difference to your 11k kills with exotic hand cannons (scrub load out).
