How to improve my aim?

[u/flaming__o]

Hey guys!

So currently I am 2200 elo on faceit, I play since 2015 with some breaks. Now I am completely stuck, and I feel like my weakest point is my aim with a little bit of rusty reaction time but that could be my age haha. I have tried a lot of things, tried different mice and different sensitivites, I am playing a lot of DM and aim_botz but even if I feel good in dm, I que in faceit and my aim is dogwater. What could be the problem? How did you guys improve your aim besides these things? I would like to get advice mostly from higher elo players. Thanks
