My idea for Living Dead (DRK)

[InfiniDragon]

Agreed. I don't think LD should end from removing the Doom state.

...Would also love to see DRK get a buff to their self-healing (via Cure potency and lifesteal) at all times, based on missing %HP (starting below, say, 80%), e.g. up to 4x healing below 20% HP. Call it... Blood for Blood.
From there, give lifesteal across all skills during Living Dead. With a burst phase, one should very feasibly be able to cleanse Doom on their own, while it should still be doable easily with minor support outside of burst.

You and me both, I'm mad WAR beat DRK to the self-heal gimmick because that's the thing I identify most with DRK, even over the whole "use HP for damage" thing Cecil does because FF Tactics is my favorite entry.
