It's time to kill the argument that DPS abilities keep healers from healing.

But like...does it make sense to approach the question of boredom from the perspective of 1) someone who knows all their fights and can plan them out and 2) starting new pulls on failed mechanics because we assume that's a wipe anyway?

It does make sense if you consider experience and optimization to be the natural result of playing the game. If Devs create content to be run repeatedly and make said content require a Healer then they must design the jobs to adapt to a player base that has the capacity to evolve and learn.

You say that designing jobs around the worse possible scenario for healing doesn't make sense, but it also doesn't make sense to design jobs around the best scenario for healing either, knowing how much these two scenarios will naturally vary the moment your players get to know the fights and gear up.

The fact remains Healing dowtime occurs naturally. Devs should account for that.
