The Dead Ends is yet another error in the push to make everything hardcore

[Krotoan]

To be fair, it's been a while since we've had a dungeon I can recall that had an Esuna-cleansable debuff that was actually important to cleanse (as opposed to, like, 6 seconds of poison or paralysis), much less one that had that *and* a heal-to-full-to-cleanse Doom. (Albeit in separate boss fights.)

So healers may well not even read the tooltip on that debuff to notice it's why someone dies on their first run. I try to read tooltips of any unfamiliar debuff (especially if it has a Esuna marker!), but I know that's a lot harder for controller players.

It's not really an excuse, mind you. But it is at least an explanation.

Interestingly enough, the new Healer Role quest specifically refreshes using Esuna as part of the healer role experience. .. This is probably why.
