Not sure why but I haven't thought about this until I read this thread, which is surprising. I am now almost 100% positive I have seen people doing this in cRPG. Don't remember names, but it was on the duel server.
I had just been told that people do "feint patterns" or "feint routine" or something like that, where they do 2 right feints, a left feint, a thrust feint, and then their real attack, and that's their style, the strategy being when somebody gets used to it they can mix it up or release a swing anytime, and subconsciously, it's harder to react. BUT, I saw somebody doing three different routines (he was dueling me repeatedly lol) and when I figured out that he did right + left + thrust he had 3 more feints, right + right + left 1 more feint, etc.. and was able to kill him 4 times in a row, at which point he stopped accepting. He probably repeated the exact same chain of feints, with no reaction to what I was doing, other than to (attempt) a block. A real, skilled player, would have easily chambered in place of a block, or mixed up the rotation/routine with a real swing somewhere in that chain since I was blocking in the wrong directions until the attack I was expecting.
E: Also, being familiar with macro programs, they can be very advanced, nearly impossible to automatically detect, (unfortunately) due to the addition of random elements. It's actually fairly easy to get around the common programs like PunkBuster. Most, and the ones that I assume most WB/cRPG cheaters use, would probably be very easily detectable however.
E:E: oh yeah, OP, you don't have to click in those boxes, just a small zig-zag going down to the corner of the screen would be enough. Right, down, right, down. etc. going diagonally is probably counter-productive since it would be harder to accurately get a side-swing or thrust when you were trying for one.
It's also not really about "fun" I don't really know what it's about. I knew a guy (Friend of my brother) who aimbotted in TF2, and several of them (3 - 4?) used the infrared skins (which are legal wallhacks essentially) and they didn't care. Dude who aimbotted actually got his steam account banned repeatedly, he just paid more money and got his account unlocked every time. I think it has something to do with trolling, like, HAHAHA I just owned that guy who is good, he thinks I'm good but it's hacks! I will never admit it though!
