I did read that post and he makes valid points, but way I see it is the bands aren't metal, and Wacken is a metal festival, so these bands shouldn't play. I take no offense to your comment either, having grown up here I can't really help but agree with you for the most part, but that's a different issue. I think if you were looking at this from the same perspective as someone like myself you might understand my discontent with these bands being on the bill. I'm making an assumption (and correct me if I'm wrong) but as far as I know Europe didn't get a tour where Amon Amarth opened for Trivium and played for only 30 minutes, or get shows where fans have to sit through sets for bands like Slipknot to see a real metal bands play for 20 minutes. Wacken is kind of like an escape from these bands, as well as a rare opportunity to see bands that just aren't big enough to tour in North America, and to see these American bands being added to a festival which metal fans in the US have nothing but complete respect for because they've managed to keep it so pure isn't exactly reassuring that the metal scene in Europe is going to consistently be something we can look at and say "Well at least they're doing it right" whenever a new metal-core band gets huge over here.
