Absolutely, back when I gamed all day and got good at older CS my gamesense was my strongest asset, when I feeling good I felt like I was wall hacking and pros would have even better sense than myself of course.
I have watched countless hours of pro 1.6 and CSGO and other games, the only thing that bothers me about CSGO especially during 2015-2017 and a lesser extent today, is the weird illogical mouse movement for some of these pros, some pros have had countless examples of weird shit and most pros say for example f0rest has nothing weird about him.
During this time we had locks, shaking and other weird movement, but past 2 years these things have dramatically become less how is that possible?
Flusha excuse was "i lift my mouse a lot" well he sure as shit doesn't lift his mouse now does he, I can't imagine he changed his aiming style overnight.
So all this weird mouse movements have been minimalised, I can think of two scenrios.
The players were warned behind closed doors to stop, which is the smart thing to do to keep a good image of the game.
Or the cheats are smarter.
I struggle to believe that CSGO has been dirty in, match fixing, coaches bug, ghosting, ddosing etc but the only clean part of the sport is the players themselves.
And for the people who want proof and will defend their heroes to the death it will never come out.
The only proof you're after if it either comes from players mouth or if valve starts banning people which will never happen because it's horrible business.
