I honestly believe that the devs aren't going to touch DRK for PVE until maybe either 5.3 at the earliest or 6.0 at the latest, and even if they do make adjustments on DRK they just make it even more boring than it is right now...

I also do not care for tank changes for the rest of the expansion because of poorly changes to tanks were made with maybe 2 tank being an exception past certain levels, but they way they did tank changes makes it impossible to actually go do older content synced as a tank because at most levels, tanks only have one combo that really matters...

All the devs had to do for tanking in terms of enmity management was remove enmity management from everyone that wasn't a tank, keep enmity combos in the game, keep Ultimatum role action and buff like they buffed Provoke, delete Shirk from role action and only add new abilities if it doesn't cause more ability bloat or ability pruning, otherwise just add more traits...
