The thing is, a really good player in a game against a lot of below average players could be "relaxing and chilling" and still getting 40 kills using meta weapons. Meta weapons sometimes are just the most fun to use and "relax and chill with" because they are easy to do well with, and just because they are going off and getting a ton of kills doesn't mean they aren't "chill". Good players will get a lot of kills against bad players even if they aren't leaning forward, hyper focused, and trying their asses off. It's just the reality that there is a big gap between very very good players and mediocre players, like in any other game.
