The Problem with Healer Feedback, and requested changes

[Archwizard]

Sure, but... not all skills interrupt combos anyways. I don't want to see combos for healers

To be clear, I mean "combo" in the classical sense of "any combination of attacks or effects", not specifically combo actions as is common to melee, tanks, RDM, etc.

For instance, the order and pacing in which Black Mage performs its spells is quite particular, despite not being limited by combo actions, and any interruption to its rotation is... jarring... as a result of that careful timing. BLM not being alone in this by a long shot, of course, due to the number of time-management gauges or uninterruptible burst phases available to almost all DPS.
Basically, the simplicity of existing healer rotations is to prevent you from digging yourself so deep into your attack groove that you lose a significant amount of momentum while attacking.

Which to be clear, "not losing momentum by stopping to heal" is an ideal approach to healers, with the majority of the issue being taken towards their current simplicity to the point of homogeneity. Even something as simple as use of procs or more active/engaging DoT management would be able to tackle this without creating a burden of "sorry I couldn't do my job because it was a significant, personal DPS loss."

I suppose you could theoretically play around with, say, setting conditionals for certain healing effects that turn them into a personal DPS gain, however... things like spending Lilies when your target is below a certain health threshold for a bonus, for instance? ¯\_(ツ)_/¯

Nor would all combos need to path only into other offensive skills. Glare->Cure II, for instance, could also apply increased Defense, extended max HP, or... further sap Accuracy from enemies in an area around the heal's recipient, etc. Biolysis -> Adloquiem could cause enemies striking the target to be afflicted with a tick at a time of Bio (stacking up to the original duration), until the Adloquiem is consumed/expires. Etc., etc.

Hell, for WHM and SGE you could play around with having Freecure proc from Holy/Glare or have a chance to force a Lily pop, or having Dosis/Dyskrasia proc to force your next healing GCD to crit.

Having a healer that is based on keeping up buffs on people would be good though IMO, just to satisfy the 'I don't want to do damage!' healers. They don't have to damage, they can just keep rotating Bravery and Faith on people for their rotation instead of Glare on the enemy. Or would 'buffing ally's damage' be too close to 'deals damage' too?

Isn't that... literally the point of AST?
