Essential Dignity, timed correctly, has a stupid high potency. I'm not saying it's worth a Benediction on a WAR that Holmgangs with all their HP buffs on, but still. Right now you can instantly give back 40K HP (and it's more than enough). It has a short Cooldown, and you can work around it with your Earthly Star or a Lady of Crowns.

Benediction has a high CD, and heals perhaps too much, compared to the average damage output in the game. I'm not really envious of Bene when I play on my AST.
