It's well known among the tank players that LD is the most hated of all the invulns, mainly for the playerbase because both: A) it involves the player dying and B) this happening without any input from the tank player itself, who is solely dependent on their healers.

Setting aside the discussion of whether o not any other tank would survive post invuln without external aid (we can all agree that they wouldn't, or would, but not for very long), i wanted to to make a suggestion on the OF that i heard outside of it (idr the name of the original poster unfortunately), of a change that keeps it in line with its current goal, and deals with these two problems, in a few steps:

1 - Keep the effects of Living and Walking Dead, but make Walking Dead a true invuln;
2 - After the effect of Walking Dead expires, the DRK player deceives a DoT on him (idk, name it "Call of the Dead" or something like that), that will tick for 25% of their max hp every 3s, including when the dot is placed on them.

That way, both the time to mitigate it is extended, which relieves pressure on healers, and the drk player can actively interact with their invuln via TBN (for 25 or 50% of it, if timed properly), which keeps it in line lore wise, and playstyle wise, no other changes required.
