I know there aren't nearly enough dragons and trolls and elves and unicorns for your liking, but all things about PPUSA considered, they may not be an ultra-risky booking, but Amorphis > Evergrey, Kamelot, or Symphony X playing yet again...
This is the exact and only reason I will consider attending again.
PP is a cool concert experience and a fantastic venue. But I can find better ways to spend $700-$1000 then see bands that I don't like/know I won't like. I don't need to spend that much to "socialize". Call me weird.
