[Suggestion Thread] Unused Mechanics (A combined effort by everyone)

[Fevelle]

Low potency, instant cast healer with faster GCD. Relies on spamming heals that have secondary buff effects.

Healer that relies on distributing damage taken by target to the whole party + AoE healing toolkit with various potencies. (kinda Arithmetician)

HP based DPS, uses HP to deliver powerful attacks (classic FF Dark Knight)

"Crafting healer" - has set combinations of skills to create and use concoctions to heal allies (think FFV Chemist using something like the Mudra System)

Any time an MMO introduces an Instant cast healer (not an occasional instant cast, their primary heal) I will always play the living heck out of it lol. It's the main reason I dont play healers too often. (Might even play healer more than tank, now that I can glamour some armor on them.)

Low GCD healer. We have 1.5s GCD melee, but I dont think any caster does this now, which is a good point to bring up.
Also adding multiple heals, with identical potency, but different short term buffs is a nice idea, adds a sort of "rotation" to healing. (If you're into that sort of thing) The potency would need to drop 40%, to equate the typical potency of the current healers.

This 2nd part I also agree with, about AoE healing, I'll just need to think of a way to simplify it when I write it up. (Was originally thinking of this for a tank, but slightly different)

There has been classes that used up HP, such as THM in 1.0, but they removed these features, most likely they will refuse such an idea if presented again. (It was suggested for DRK before they switched to MP) LNC's blood for blood was far more dangerous to use before, and because players kept dieing with it on, they nerfed it to not weaken you so much.

This last one sounds like you're saying "Why not the mudra mechanic on healer?" (or tank to cover every role)
I'll put a footnote somewhere.

We could also have the original Chemist system from FFV. Since all these Key items slots are unused, a healer class that could stock special potions in the key items tab to use with a Mix skill mid battle would be pretty great. But I think a lot of people would complain, even if said items were free of charge.
