Seems like you never played with that low sensitivity. I guess you tried to lower it from your 2.5 to 1.3 or smth like that, and you couldn't even move, so you switched back. If you are really used to a low sens you won't have any problems. I play with 1.3 for 2years already and sometimes it seems too fast for me, I can easily clear all corners and shit(1onX is not a problem at all for me). You just need big desk + mousepad and you are good to go. And your lovely map training_aim_csgo is just to improve muscle memory. I can easily flick on all the circles as you need max 90 degree turns here.. 100/100 guaranteed. Btw seems like you are pretty low player at this game, so if you change your sens to 1.3 you will become beast like I am: global, ESEA A-, faceit 10lvl, 4k hours, CYA.
