I suggest a system that warns, kick, ban players when the player is clicking above 11 cps for about 5 seconds. With this, the keymapper will be useless and cannot auto-click.
I saw a lot of people that use keymappers for pvp, and it is so annoying.
Um 11cps is very easy for many people to get? I don’t play many pvp games but I know that you don’t need to be hacking to get 11 cps. Like what Rare said, maybe something at least double 11.
