Blood Price should have a defensive mitigation added to it.

Sole Survivor should have a MCH Wildfire mechanic change, that compounds damage into healing at its expiration -- It's currently not viable for raid encounters with such a long CD and useless on a boss-only encounter.

Abyssal Drain/Unleash should be re-worked -- There's no sense in having two AoE Enmity abilities that hardly cost more/less than each other.

Shadow Wall -- Compare to Vengeance = 1 min longer CD, Same Reduction, No Additional Effect, Lasts 5s shorter -- How did this fall through the cracks?
