Soilwork and Scar Symmetry are also legacy bands but very few people in the metal community seem to think so. They still consider Arch Enemy modern when they're not. That's not a reflection of the quality of their music, but metal has stagnated big time because of this attitude. That entire wave of bands are as old now as Testament were in 2000. Think about that. As I said I feel it's because metal has written itself into a corner by defining itself so narrowly when it never used to. Heavy music has moved on, it's just that metal people haven't and it's going to kill the genre if people don't start checking out other kinds of heavy music and reincorporating it back into the umbrella term "metal".
