To be honest, I can't understand the Devs reasoning for 1 button dps rotations for the healer jobs:

Noobs, Semi-AFK-leechers and mentally challenged players won't do their DPS rotations anyways and just do the basic healing spells. They should create some DPS rotation and make it so that the rotation does not get interrupted when a healer does his healing spells (and casting a healing spell should prevent the rotation from running out). Problem solved. A more interesting rotation for healing downtimes will make healing more appealing for dedicated players. The only DPS or Tank player that will currently switch to Healer for dungeons is either eating or is watching something on the 2nd monitor.

I haven't played healer in Shadowbringers at all except for leveling them from 70 to 80 because I got frustrated with casting Broil all the time or becoming a breakdancer when spamming Art of War. Currently, I would rather do the Praetorium than being a healer. Even playing a Paladin and healing everybody with Clemency is more fun than the current healers now.
