How would you solve the boring "damage rotation" of the healers?

[Aravell]

I do get a small amount of.. some feeling or another from this line, maybe schadenfreude or something similar. Because I do wonder for WHM, 'what healing plan?' Anything that happens to us, we respond 80% of the time with 'Rapture'. The 'healing plan' is something the other three healers do, rotating through their OGCDs, WHM just goes 'Magic Missile! Magic Missile!' with the same heal over and over until they have no Lilies left, at which point it's Cure 3 or Medica 2. I remember my 'healing plan' as a WHM in TEA. It was 'Temperance at 5 stacks, do 4 Medica's, use 3 Lilies with PI, spam Cure3 until phase is over'. Compared to my Noct AST partner who was doing some mad gigabrain stuff on their OGCDs, use Star here, pop it here, use CO on this stack count, use CU to cover point A to point B. WHM is just bruteforce healing power, and that can be useful in prog, fun in prog even. But once you don't NEED that power, it doesn't have much else to keep it feeling engaging.

The one time I felt clever on WHM in recent years (like the past 4 or so) was doing UCOB to help a friend's prog, and I had the idea to purposely hold Assize (at a damage loss), so I had one extra 'heal while moving' to cover Blackfire Trio's stack mark damage

I believe that's the fatal flaw with WHM, it's way too simple. While simplicity is not inherently bad (The PvP kits are extremely simple but they at least have heavy interaction), WHM does suffer from too much simplicity, most of their healing spells are just flat "Heal X amount" spells, the damage side being "Deal X damage" along with every healer also isn't helping WHM.

All that said, I don't think WHM needs to be really complex, just some nice interactions between things, delete some redundancies, add a couple of situational stuff, just a general rounding out of the kit. There's nothing wrong with the image of a powerhouse healer, it's mostly the implementation that's extremely questionable.
