Please just... Just change Living Dead

[PyurBlue]

It's kind of telling when the only time I've been able to get off Living Dead in dungeons in recent memory, has been from 100k needles in the 2nd add pack of Sabotender Valley, and from the Knockbacks from the final bosses in both Skydeep, and the 7.3 dungeon, because otherwise, I get healed through it, even with having a short macro about it.

If you're getting healed through it, is there a problem? The healer was about to output enough to heal you, so maybe LD wasn't needed at all? That feels like the norm for most dungeons. If I see a DRK go into LD I'll try to let them use it but the truth is whether it gets used or not isn't a big deal in dungeons.

If you know that your healer is eager to throw everything at you then you can wait them out. Let them use all their heals, keep track of what has been used, and then use LD.

for myself I do see a tank having to invuln as a failure on my part

You shouldn't. Invulns are just another cooldown. I try to use them as much as possible, or at least I did before tanks became so strong that using anything other than their short mitigations became optional.
