I just recently got back into counter strike, haven't taken cs2 seriously, but I have over 2000+ hours in CS:GO and peaked Legendary Eagle a long time ago.
I honestly just wanna see how bad or good I am at a certain competitive level. When I was grinding CS:GO, I never really cared to learn about aiming, but after playing a bunch of shooters, I ended up putting over 100+ hours in aim training. I'm not saying I'm that much better now, but would just like to test my skills after not really playing any more shooters since then.
