To be honest I think a lot of classes could use "spec" culling. ... We don't need two dps specs that force us to respec every other tier ... just to be "optimal" ... DK could have just Blood + Unholy ... Warlock could have just Demo + Destro ... they could cut a spec for everyone. make classes have one option for each role. Then you dont need to worry about that third spec, which you dont currently have gear for, and dont ever use, that is suddenly top dps... and less annoying to play this tier. But then mid tier... they change everything because a particular trinket make the first spec better along with the changes. Or 3/4 through the tier some guy finds a borderline exploit which Blizz says is clever game mechanics which makes the second spec better again. Its annoying.
