I doubt it. In my personal opinion rogues should be up there at #1 or #2 with Warlocks because they are pures. Combat would be King on single target, sure, but I believe they'd make Assassination not lag too far behind, and make it the best for AOE fights, by a good margin. Then round off Subtletly as the "hard to master" spec with the potential for very good DPS if played masterfully. That's how I'd envision it.That "plan" would just make all the other specs obsolete and combat the king of PvE in all enviroments.
