Unlike most of the achievments, first of all, its more like something that depends if you actually do have an hability to click really fast and not an achievment that anyone can obtain if they try to. Seriously, its not every person that can click 15 times per second or has 2 mouses or a complete keyboard that can do certain commands to make you click really fast. (Seriously, the function for unlocking this achievment is even called '' Autoclicker.Detected. '' or something like that )
The problem is that we would need to have an achievment to replace it anyways... And i dont see any one that could take its place.
