Healer main here.

I personally hate LD, the fact you need to recover the total HP of the DRK in order to purge the debuff is seriously annoying on AST and especially SCH.

Ofc on WHM it's a joke but having to essentially force WHM/DRK comps is what SE should avoid altogether. But having Benediction just makes the invuln a joke, since it defeats the urgent nature of it I suppose so why not change it?

At least with GNB/WAR it's something that can be fixed with an OGCD.

I suppose they can't find more unique invuln skills as GNB's just punches itself in the face (but really it's just a combination of Holmgang and Hallowed)

It's just a headache on non-WHM healers and people aren't always going to want to play WHM or should they be forced to for the convenience of dealing with LD.
