I can’t imagine a situation where they could both make healing interesting and also allow for a static healing rotation, because they would have to tailor the fights exactly to the healing rotation which makes healing a nothing burger

Like imagine if they decided to time a random mechanic to be AOE when you are in your “spam adlo” part of your rotation

a DPS rotation that gives a healing buff afterwards sounds like a decent idea but I can see it being unwieldy (sort of like a modern cleric stance)
