Kid, why are you even posting here? You werent even around back then.Tbh at that time, almost 8 years ago, no one really thought it was "an invention"... so no one was really the one saying "I invited combo". People will always be selfish and greedy. At that time, most of the people... the people that were pioneers of combo thought it was a bug and kept it to themselves, because they clearly saw it gave them advantage over others.
Either way, if you are looking for the pioneers of combing, you need not look at USKO... you need to look at MYKO. Even though I played from the start, I was 14, and not exactly paying attention to my side bar of damages. I can give you a good guess of who those people are, only because they used to be the top killers on an even server (because it was new)... but even if I did, it doesn't mean it's true.
