We really need to talk about Living Dead

[Rongway]

You can visit Healer forum to see how they explain it how among the invuls they hated it the most.The one who shouldering the burden know best. No need to trivialize it.
*But just in case you decided not to look it up I'm going to pontificate

You can visit my character profile to see if I've at least taken the time to level healers, or checked the healer forums to see if I ever participate there, before assuming I don't understand how healers think.
*But since you didn't, I leveled all three healers immediately after finishing the story on RDM and I heal roulettes regularly. No need to be truculent.

The healing window is also more lenient and less stressful and ultimately BETTER than with living dead ... It is the worst*

Obviously Holmgang and Bolide are "better" vis a vis "more lenient". Out of four abilities, one of them will always be "the worst", and healers will automatically label the one that takes the most work as the worst.

But it's not bad just by virtue of being the worst, and it doesn't take that much more work.

As for the others being "less stressful", this should be a non-issue. The first thing the healer should look at when getting into a duty is the job icon for the tank, which will dictate, among other things, the appropriate plan for dealing with the tank's superbutton. If you're in a party with a DRK you should already know that it's possible you will be required to heal them to full in the span of a few seconds, just like if you're in a party with a GNB you should know that you don't need to be alarmed if their HP drops from 120,000 down to 1 in an instant. The answer to the potential stress of these two abilities is awareness and readiness.


Would Living Dead benefit from some improvement like Seraphor's suggestion to have 50%≤healing<100% give Weakness instead of KO?

Yes, absolutely. (And Seraphor's specific suggestion made me go, "Oh, that would be a neat way to handle it.")

But is Living Dead just brokenly bad? I don't think it is.
