AoE pulls are pretty simple and I'm surprised it wasn't mentioned, but Abyssal Drain is godly for AoE pulls. You can pop a CD as you're running in, grab mobs with Abyssal Drain/Unleash/Unmend, whichever is easier as you're running. You can Dark Arts Dark Dance as you're running as well. Once you get them where you want, pretty much pop Blood Price and spam Abyssal Drain primarily, but Unleash for quick aoe aggro without the need to target first if you want. You can alternate Dark Arts on every other one and the mobs hitting you with Blood Price up will keep your mana up while the DA powered attack will help keep you healed up. Feel free to weave in Dark Passenger with DA if you want.

Abyssal Drain's higher potency along with the higher cost than Unleash being negated by Blood Price is what makes this attack so good, and you will not lose enmity, while easily keeping yourself healed up.
