IMO the key difference between Triage heavy gameplay like old WoW and FFXIV in its current incarnation is the power and abundance of AoE heals with huge ranges and very little cost or penalty associated with them.

I’m pretty sure you could comfortably heal any dungeon, 24 man and likely extremes too with only AoE lilys, Medica 1/2, assize, asylum and Cure 3 on your bars. I’m actually not even sure if it would make most stuff any more difficult tbh.

That’s a huge problem and a big part of why healing feels so mindless.
