TBN & WD probably wont be fundamentally changed (in 6.xx)

[ForteNightshade]

... They completely overhauled Ninja's entire Mudra system last expansion; changing them from oGCDs to GCDs, which fundamentally changed the job's rotation. And they did this during Shadowbringers. Both Monk and Summoner have become completely different jobs from their predecessors. Astro's original card system was abandoned and Bard went through Caster phase.

Changing Walking Dead or scrapping it completely wouldn't even be a fraction of the aforementioned changes I just listed.

Similarly with Walking Death, they put effort into it and its an interesting difference like superbolide. In theory it has the potential to be the best oh-shi button in the game cause you have 10 seconds to *catch* your invulnerability, and your invulnerability *starts* when you reach 1 hp. Thats actually... really awesome. Plus again, they put a lot of work into it.

Quoting this specifically to say, no it doesn't. Even theoretically, Living Dead has always sucked. You never used it as an "oh, crap!" button due to the healing requirement almost ensuring your death. The whole "catching your invuln" as you describe has always been a jebait. It had miniscule value at best yet was still woefully and hilariously outclassed by Holmgang. Which is made even more apparent now despite Holmgang being nerfed to 4mins.

They didn't put a lot of work into it. That's nonsense. They tried being unique without considering the gameplay implications and ignored how widely superior Holmgang has always been. "Flavor" over functionality is bad design. A tank invuln should never kill the user. At least not when there are zero drawbacks to every other tank. All that does is create an imbalance. If it weren't for Dark Knight's absurd damage output right now, it'd be a dead job because of it's janky "flavor". Buff PLD or WAR to GNB levels—which is still weaker than DRK—and you'll see the job's player rate plummet. Nobody likes the "flavor" of LD.
