In a 5 man with the 15% buff, I could probably do at least 7k DPS just white hits. Now doing my full rotation, I usually end up anywhere from 22k to 27k. The point here is ... You're meant to have to at least TRY to clear the dungeon, even as a DPS. If you're just auto attacking and get killed then complain to blizz that you need a buff ... well, you're just a retard.
