There are also options around buffs eg heals or shields that give small short term buffs or other buffs like a team-mate targetable Arms Length spell etc etc. You could also get fancy with queue and mirror type spells like enchanter style classes in other games, ie the class of spells where you pre-cast before a heal to modify/duplicate/ricochet it. You could also take a leaf from sage's style and adjust some heals to be target at the boss instead of the player, ex heals that are part of the DPS rotation (spell does 100 Pot dmg & -100 Pot dmg to target's next attack)
You could argue these spells aren't "needed" because after all you can just cast Esuna followed by an oGCD heal or just be lazy and brute force heal but there's probably still some room for people to play for efficiency of time/mana.
Tl;dr I think the main direction left available to them design-wise is heals/shields with special effects that aren't +X HP, ex: Heal + arms length, Heal + shave death debuff timer, Heal + reflect dmg, whatever. Personally I also think they need to make the DOT style enemy debuffs put more pressure on the healer, some fights have this but there is still room to increase the global pressure on healers caused by bleeds/poisons/burning etc, things that cause long term efficiency pressures without just being another buster attack. Instead of making an AE that just blows people up give it a vicious burn/bleed that lasts a LONNNNG time.
