I was rooting for Epsilon the whole game, and was happy to see them win but I'd have been just as happy for Mix^ to win because if they did, they'd have deserved it. It's amazing that teams like Mix^, 4G and iM could travel so far to play in a competition where the prize money would not make up what they had spent to get there, and that iM could find the motivation and means to improve after dominating their scene for so long.
Yeah, Harbleu and lots of other players talk a lot of shit but it's a normal part of competition and while it might lose people some friends, it won't directly impact on any professional's performance.
Harassing players though is just unacceptable, whoever did that is a fucking idiot and seems to have missed the point of the whole event as far as TF2 is concerned, to see how the best teams compete unimpeded as well as having a good time. The TF2 community didn't spend all that money and Mix^ didn't put so much work in just to get messed with by idiots of any nationality.
