Living Dead and other DRK QOL in 5.3

[cactuarzzzz]

Soul Survivor would end up being used as part of the mitigation rotation, (20% bonus healing plus 30% of your HP restored? That's better than Clemency) so you can't guarantee that it would be available to use just before you need to hit LD.
Plus you need to use SS before LD or that 30% HP heal won't save you, so your invuln becomes 2 buttons... that you need to hit in a pinch. Surely that's making things more complicated?

Are you intended LD to be a panic button?
