Would Discipline Priest Mechanics work in FFXIV?

[Brannigan]

melee healers do not work in XIV. They would have to redesign old encounters and never use a mechanic they have used in multiple fights in the future to accommodate for melee healers.

Ifrit EX, Leviathan and Gordias 4 are all examples of why we will never get melee healers.

You do not need to redesign old encounters because the gear is worthless from them and power levels are so high compared to when they came out that they are nearly trivial.
