Most cs pros are washed up grandmas and have reaction time of a turtle. You have garbage players like s1mple being called "the best awper", you have flamie rifling on top 5 team while whiffing m4 spray 1km away from target like hes playing with 300grams mouse.
You can clearly see that most cs players are lazy 30 yo bots with 250+ reaction time by watching streams of getright or s1mple, you can also find a video that shows average rt of cs player. CS players are actually the worst out of all "pros" not only in terms of mechanics but also brainwise, the only team that uses brains ingame and in preparation is astralis, only took cs-degenerates 20 years to reach level of coaching/mental/physical preparation of lol/overwatch players (2 year old game).
So maybe in 2-3 generations they will start working on their reaction time and we might finally see s1mple's son in his early 20's finally hitting 160 ms reaction time in perfect conditions on 600hz monitor, while in other games like siege 3 or overwatch 3 most players will average 100 ms because there will is no room for shit mechanics in these games. If you miss a shot you get replaced by korean ladder god that has his crosshair on enemy neck 90% of the time and spends 8 hours a day grinding kovaak.
The only time cs takes a bit of reaction time is when you play on 200 ping combined with 1280x1024 stretched @ 50 inch TV and you have swedish pig wide peeking you while you afk in common angle.
You can be top 10 in this dead game by playing off angles and have good crosshair placement just like ropz and electronic do (actually skilled players, not bots like zywoo or device that are only capable of abusing bodyshot telescope gun).
