Their DPS is honestly pretty competitive

While some specs may do slightly higher damage than other specs within a given class, the differences aren’t so great that you’d really be holding your group back if you played your World of Warcraft Gold favorite talent tree instead of the one with the highest DPS logs. In almost all cases, individual skill, gear, encounter specifics and Internet lag will have a bigger effect on your DPS than your spec choice (and often your class). Seriously, try Frost mages. Try Subtlety rogues. Their DPS is honestly pretty competitive.
