Right, so, to steer the long-form debate into a wall, let's address the facts we know:

---------------------------------------------------

1) WHM is doomed to hold the baby rattle because the developers want it to be the simple healer anyone can pick up, while simultaneously reflecting this decision onto the entire healer role rendering it null and void.
2) Healers in general have been reduced to a large portion of their gameplay being nuke spam, upwards of 90% of your uptime in some extreme cases, but always the majority of your casts in others. They currently have a dot that takes up another chunk of your casts, and will likely be removed in 7.0.
3) The game has a whole two class designers, and in a Live Letter prior to Endwalker the creative director said in no uncertain terms that they're not making healers more complex.

---------------------------------------------------

What do we expect of healing in 7.0? Does anyone have hope that the dev team will go against the direct statement of 'No' to additional complexity made before Endwalker? What are your plans for if they hold true to that? Will you completely quit the role if you lose Dia and its derivatives and get reduced to truly one-button spam? And moreover, what do you specifically want?
