Mostly higher ranks like 200 and up who just keep killing you over and over again. These people care about their KD ratio too much and take it too far with it. They kill you right away after you spawn, kill any player in their vision, destroy cargo and stuff like this. Expect to see a KD ratio on them that is higher than 1.00 and that is how you know they are a tryhard.
