Once you have Abyssal Drain, you shouldn't spam Unleashed for aoe aggro, 1x Unleashed into Abyssal Drain for more aggro sustain. Generally DRK still the same with a few tweaks. DP still good (240pot x enemies hit is really nice) for dungeon runs. If you tend to go out of Grit, you most likely still need additional aggro and DP kinda helps that for initial pulls. Generally always have 50%+ mana pull to use more aoes.

Other than that, Quietus is great if paired with Blood Weapon for dungeons where you can reliably hit multiple mobs for more mana.
