What is kjaebye's main paid occupation? Csgo. So what is he? Professional. Also pro for short.
Who is not a pro? You.
Mir is the top 1 player with a silencer. He never switched from it, he's loyal to his weapon of choice and he should be praised for it. Such a fidelity, all others would switch back and forth, jelly boned.
He is one of the best or the best M4A1-S player. I remember watching Launders' video about mir and he was just killing it in Mirage with it. Insane player.
Aerial also used it for a long time and I remember when he was killing Astralis outside in Nuke with it during the finals when ENCE won against them at Blast Pro Series Madrid.
