Bl Sniper. You will no win anymore
Why? He has rope skills, He just wont be able to tap as fast. He can use 1 finger and still be good or try to fr.
I feel for all the people with key lock and bad spaces and the people that need to use 2 spaces in order to get fast taps but the best way for a even playing field and no cheating and scripts is to outlaw all programs scripts macros etc
I dont know how else you will detect this
So you assume everyone with fast taps has to use 2 space bars or remapped his keys? That's a little bit over the top.
For me this sounds like the ancient witch hunt, someone looked suspicious, let's burn him!
But just like you said, you won't be able to detect who is using remapped keys, the said autohotkey script or 2 space bars or whatever. Why? Simply because you don't have a camera installed in his/her room to see it, and I don't know how Cybershadow would be allowed to install a RAM scanning program into the W:A client. Because as of now we don't have a terms of use accepted that allows T17 to scan our RAM for the program (or programs if there are more).
And that is very unlikely to happen in my opinion, or else it would have happened years ago because cheats/macros have been around since the very early years of W:A.
