A CPS cap/limiter is a terrible idea for quite a few reasons.
1: No one can agree on what CPS the limit should be
2: Everyone here is suggesting stupid limits for CPS such as 15 and 16 when I'm friends with people who can click 17-18 jitter consistently without any doubles or a broken mouse
3: A 20 CPS limit (Which I see as the most likely number that will be set as the limit) is problematic for a few reasons. It's super easy to get a 17/18ps auto clicker which the anti cheat wont flag for and 20 CPS is too low for players who already click fast and double click. For example, I can click up to 15 CPS no doubles, so why should I be restricted on my ability to double click where someone who clocks 9 without doubles can double click and stay under the CPS limit. You could simply say to "click slower" but it's quite hard to do in PVP considering I've built up all my aim and muscle memory clicking at a speed which is natural to me. The only thing a 20 CPS limit achieves is allows people who naturally click slow to cheat and people who naturally click fast to get punished
4: All the best players and content creators on the server double click in PVP, so banning so will lower the quality of gameplay coming out of your server and make the server less appealing to new players and aspiring content creators
5: Too much server lag on cube so the CPS will stack like it does on zeqa and false flag people
6: Forgot to mention this yesterday so I'm editing it in now but there isn't a working double click prevention software that anyone can use (At least not anything open to the public). Sure, there is DC prevent, but DC prevent doesn't cancel out double clicks, it makes a 55ms delay after you click where you can't register another click until the 55ms is over. This means that using DC prevent, you can only achieve 18 CPS no matter what you do. This doesn't sound too bad because no one really hits 18 CPS right? Well it's true, but DC prevent ends up cancelling real physical inputs, not just double clicks. Someone is going to ask how I know this for a fact so I'll explain now to save myself time later. So butterfly clicking or burst butterfly clicking is a method where you alternate your index finger and middle finger to hit your left or right mouse button to accelerate the rate of clicks being registered. When someone butterflies, there is usually a smaller gap between when your first and second finger hits than there is when you finish the butterfly motion, raise your fingers up to butterfly again and then hit your first finger. Due to the clicks being closer together in this clicking method than that of jitter clicking at the same speed, DC prevent cancels these clicks out. I can click 15 CPS without doubles on a mouse and when I butterfly on DC prevent, my clicks can get cancelled out as low as 7 (Although usually my CPS will stay in the 9-11 range). If I have my index finger on my left click and middle finger on my right click however and complete a butterfly motion so my index and middle fingers hit their respected button, I achieve an average of 6-7 on each side easily (Which adds up to 12-14 CPS combined). DC prevent and other softwares are either not available for everyone or don't work which means that people will have to buy new mices or they can not play cubecraft. Pay to play is a lot worse than pay to win.
Please do not add a CPS cap/limiter. It is stupid and there are no ways around double clicking for a lot of people. Some mice like my own do not have a working debounce time and double click prevention softwares are absolutely terrible.
