you look like a plat diamond player. the aim speaks to it. the movement and awareness seems like gold level.
in DM your movement is so weird. it's not clean. and idk how to describe but you just run around you're not even playing it looks like you're just touring the map. Like a headless chicken. i know deathmatch isnt a serious thing but this kind of stuff really shows. it's like a fundamental thing, dm trains your fundamentals: your positioning, awareness, and ofc aim. you're just running around like you're not even expecting to see anybody. then you die, or you get one guy and get killed from a different angle.
that's just my take on it. i need to see ur util usage to be sure of your rank/potential.
