Dude, try to get better at PvP. I was just like you not so long ago. I had a 0.20-0.30 k/d when I started PvP. Destiny is basically the first FPS game I'm enjoying and my first PvP FPS experience too. The Iron Banner forced me to go in there, to learn the maps and get better at PvP. I'm now a decent player and regularly get a k/d over 1.2. I'm now completing PvP bounties which greatly helps lvling up my weps too. Try it, it adds more variety to the game too. It's all good once you learn the mechanics. Now I'm trying to get better every PvP games, it's a challenge and a great experience.
