Would love to see something like a reraise as now if healer dies in a lot of fights it is pretty much the end of that try.

Aoe removal of effects for higher cost.

More variation in healing skills like single target heal with regen for example. Or regen that works different in small to larg hps or the other way around.

Certain traits like if you crit heal target in party with lowest hitpoints get healed for a proportion aswell.

More instant heals or expensive heals with shorter cast time.

Overall coming from WoW i find healing atleast on white mage a bit boring but that is also because of how the endgame mechanics are made with all the running, sometimes hard to heal effecient in between running for your life.
