Well, it's all subjective isn't it?
To me, the definition of a player encapsulates more than just skill. I think Demon1 is a highly composed player who does not succumb to pressure and is extremely lethal in gunfights. I don't deny that he might be if not the best duelist we have seen in ages. My personal philosophy and beliefs or whatever involves evaluating professional e/sport athletes as a whole person. Be it in game, or in reality. For example, I care a lot about sportsmanship, and while some people might care less as they find it entertaining or banter, I don't, and that's a me thing. Therefore, I do rate Demon1 less because of the behavior he has displayed on the international stage. However, I'm not saying he's a bad person or whatever, he just isn't the kind of character I enjoy watching, and that's completely on me! We are all entitled to our own opinions and the least we can do is respect one another.
