you cant compare classes. its specs. You cant compare fire with frost, you cant compare arms with fury, you cant compare ele to enh.
Thats like saying when disc is a god and holy and SP are trash, that priests have high rep. it doesn’t work that way.
It hasnt since pre wotlk, when there was only 1 good pvp spec per most class. for a long time now theres been for the most part 2 good specs of every dps class, except DH and DK and monk, which 2 only have 1 dps spec, and frost has almost always sucked
