There are players like me who think that Healers should be inherently conceptualized and designed as priority-based nonlinear DPS classes built around the core of a spammable single-target nuke with the added notion that always losing out on DPS by casting a healing spell under any circumstance is bullshit design. I am 100% convinced that I am right on this and that to work under this paradigm could constitute a true future of healing jobs.
To increase healing requirements is dead ends thinking that will never bear fruit and that dare I say should not. It would be the equivalent of designing a class that has to clip GCDs to be maximally effective, it's just going against the foundations of satisfying gameplay in this game.
To have the ultimate goal of healer optimization be the total elimination of an entire class of GCD from your log and therefore further reduce the variety among GCDs is equally foolish - as is the idea of having healers only function properly while in high-end max level party duties.
Additionally one of the biggest issues for healing jobs is the amount of targeting needed to perform optimally. Dragoons can kind of empathize with their shiddy Dragon Sight ability. There needs to be a new mechanical type of spell introduced that doesn't yet exist in the game: Ground-targeted GCD spells that start the cast on button press along with giving you a ground marker that can be locked in at the desired location and then as the cast finishes has your character execute a spell targeting that location. Kind of like Bomb Toss, the Blue Mage spell, only that unlike that failure of a design the spell begins to cast (and thus the GCD to roll) on button press, not on location select - location is selected after. A design like this would allow stuff like Sacred Soil to be on the GCD or Cure III to function without a target.
Also to prime a target first to then later execute an ability on them without needing to target them again would be appreciated. Even auto-select focus target with a modifier would be quite nice, though not a panacea.
