Well, unlike most people Chase plays smart. His thinking and reactions are both very fast. On top of that he knows where to go and when and he usually has many players on his side (unlike me).
He knows how to play this game, every single class. Except maybe thrower, he's not very good at that.
Great duelist (although not impossible to beat) but battle is where he's exceptionally good.
However, it's harder for Chase to "shine" if there are less players and all of them are skilled, which is perfectly normal and goes for pretty much everyone who plays this game. For example, Gurnisson isn't worse player than Chase.
People get killed in many vs one situation because of greed, two crappy players can kill a "giant" if they cooperate, instead of trying to steal each other's kill.
