Why am I not getting any better

OP - don't let "kills" determine your value on this game. The numbers can be skewed so heavily, it's ridiculous. That's why you have all these hot-droppers with a * ton of kills and no wins. The whole point of the game is to win, so you need to add value to your team. When I see a random on my team with a ton of kills, I prepare for the worst. They're the ones that go off on their own and quit when they die. That's no way to play a team game. I never understood going into Squads just to do your own thing. I look for a teammate's wins because it shows they know how to survive.
