I think keeping lilies as GCD actions is ultimately a better option for WHM and adjusting Misery's potency to be neutral rather than a loss. The reason for this is because you are now encouraged to use your Lilies when you need healing rather than using Glare as much as WHM does which is exactly something that many players would like to see. A lot of people may not mind having DPS be a part of healing, but hate that Glare is the overwhelming majority of what WHM casts.

It also helps keep WHM as a low APM job which I think a lot of players also are happy with. It's really more about giving WHM more love in its value as well as its priority of tools that it relies on. Another option originally pitched by Sarixis was "Diacloud" where your regen ticks could proc Aero/Dia to apply more upfront damage--essentially stealing the concept from BLM. It gives WHM more mobility, more damage, more rewards for maintaining your regens, and more choice with their casts. This picked up popularity here on the forums because it's honestly a great way to add more depth without necessarily changing WHM much or making it harder.
