I am a better pvper than I was as Destiny was my first FPS. Simple of course... But I also had so many games at the .5 range (and still do on occasion), that my stats are pretty garbage. I also play a lot of defense for the guys I play with and often I am the first man to engage in trials, which means my k/d suffers. Numbers, and K/D specifically is pointless in objective based games. Win to loss ratio is more valuable. I may get 0.3 K/D for a rift game, but i am the first guy to protect the carrier; I will die more than I kill. I also play defense in control. This means that more often than not, every engagement is often 2v1. That also hurts my K/D. By the same token, if i dont care about winning the rift or what my other teammates are doing, kills are MUCH easier to get. So when you see "I went 34-5!" and it is a rift game, it means nothing to me. Did you win? tl;dr: K/D might have value in clash. For all other game modes, it is arbitrary.
