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

[Hyperia]

Healers shouldn't need a damage rotation, there should be sufficient incoming damage that they should be constantly busy healing the group or individuals. 80% of our GCDs should be occupied with some form of healing, the rest can be buffs or some DPS, but we should be mostly busy with healing.

I'm going to come right out and say that I believe its encounter design problems. I am also going to come out and say that not everybody can or should be a healer, its a difficult job and it should be challenging, just like tanking.

Every game I have healed since Everquest in 2001 through WoW in 2014, I had to heal and heal a lot, it was a challenge and I enjoyed it. XIV had the same feeling back in ARR 2.x but it gradually diminished the further I got into the game up through Endwalker.

I think that the Devs have spent too much time trying to make healing so easy that nobody needs healers.

Edit:

<humor> Well, if they keep simplifying healers, sometime in the future we will be down to 2 buttons. A DPS button that charges up a 2nd button that does a full group heal and then back to DPS to charge up for another big group heal. </humor>
