Sigh..
I didn't say Dragonforce were good. I rather like them, but they are mindless wankery of a epic scale. I named Dragonforce as a example of a power metal band, because they are far and away the best known power metal band.
Also, Hat, does it insult you so horribly that I assumed that not everyone knew what exactly power metal is? Not everyone is into metal, and thus isn't familiar with the endless web of genres and subgenres that particular music type likes to spawn.
