Anyone know if blocking mitigation has been increased from 20%?

I don’t think you realize every other tank save for paladin has a self heal built into their damage combos to account for the passive mitigation paladin gain though blocks. Block strength increased in the past for paladins to directly account for the massive increase in these self heals that higher damage weapons provided the other tanks.

Abyssal Drain is DRK's equivalent to Clemency, essentially. And it is complete garbage on anything less than six mobs insofar as healing done is concerned.

Aurora is GNB's equivalent to Clemency. It is a heal-over-time effect that equals out to roughly the same potency as Clemency, but its cooldown combined with how slowly the heal actually come makes it more suited to smoothing out damage over than recovery.
