Who else is worried about SE and Ast?

Though in content that actually matters (any content with an enrage), it's by far the least desirable 'sustain'



I do count TBN as healing, same as I would Galvanise, Nocturnal Field, and Divine Benison. And DRK has the potential to 'heal' up 100% of their HP every minute, which is much better than any of the other tanks can boast, on top of the lifesteal from Souleater.
You won't find many DRKs, or many fights, where you can get that amount of usage of TBN. The potential is there though, and I don't think anybody in their right mind would say no to a Benediction on a 60s cooldown.

There's a difference between effective health and healing. TBN is effective health, it doesn't "heal you". It just provides more health for a little while, if the mob doesn't go through that shield it vanishes.

And if you want to talk about healing 100% of your health every minute, PLD has that in spades. Requiescat is on a 60s CD and provides 50% healing while it's up if you have max mana. So if you were in survival mode and popped that you could have 9000 potency worth of healing in 5 instant cast GCDs which is more than 100% of your HP.

That's assuming none of those Clemency's crit, which TBN can never do.
