Priests are the best dps, mages the worst

A reader sent me a link to his site Raidbots.com which data mines information from World of Logs to see what classes and specs are on top of the dps meters. The winner over the last 60 days is the shadow priest, with the bottom place being taken by frost mages. Somehow I didn't count on making the best damage dealer when I rolled a priest 6 years ago. And I guess I'll have to respec my mage to fire.
