>for example in Dota2 it doesen't matter how fast you click an entity, because the turnrate of your character is limited, so a person clicking reasonably fast and a bot clicking in 0.01ms both arrive there at the same time. Precision also doesn't matter, because a player can click the icon of the enemy instead of trying to match the pixels on screen.

Even with turnrate, reaction time is very relevant. Reaction time allows you to silence enemies midcast, or to pop a shield, or a BKB, or some other instant measure. Turnrate doesn't mean reaction time doesn't matter, it means the direction you are facing matters.

As for precision, yes it does matter, ask any Phoenix player who gets hexed mid-flight.

People cheat in Dota in these very terms, it's absurd to argue it doesn't matter.

Unless DOTA2 is running at a ~3 tick rate (Which it's not), even taking account processing delays and action batching, a bot will always have faster reaction times than an actual player. It will also never misclick.

This problem is magnified in a shooter game, which would be unplayable with that kind of batching, but where a cheater with an aimbot is actually impossible for a legitimate player to beat.

There is rampant cheating in online chess and poker as well, you know? You can have an opinion about what constitutes a better game for humans: should it be about making better decisions, arriving at them faster or being fast and precise with your mouse but the reality is bots/assistance can make you unplayable in all of those domains.
