Healers that don't want to DPS are like DPSes who refuse to move out of AoEs.

And what's the issue with that? As a healer, when no one is in any danger (and you should know it as all fights are scripted), what else is there to do but DPS? It's a choice of 1) DPS, 2) do nothing at all, or 3) do something useless (overheal or spam Stoneskin over and over or something). There is only one correct choice here (unless you're in a very specific situation in which the best thing you can do for your group is to do nothing or do unnecessary overhealing, which can happen, but is rare).

A couple of issues with that. First, people start deciding for you when you should be doing damage without any clue of why you're doing what you're doing. Second is with the type of reasoning you employ, which seems common. Claiming they have a choice to say they have no choice.

This is a slippery slope argument, and also a strawman. No one is advocating healer play that puts DPS before keeping your party members safe. The argument is, 1) when you know your party members are safe and don't need healing, do DPS, and 2) required healing in majority of the fights is so low that there is almost always room for healer DPS.

I honestly don't see it that way. I've seen enough fresh lvl 60 DPS telling me that I should be dps'ing while I'm running out of MP healing an undergeared warrior in Deliverance or PLD in sword oath. Or party with 5 DPS, healer and one tank (most of whom are new) getting in every AOE then complaining I don't dps because they're not pushing phases and have to do mechanics.

Are you claiming that it's been possible in this game to complete Alexander Savage raids without any healer DPS when they've been released? Because I'd like to see a group like that for sure.

Perhaps not in that situation, though in that situation you'd be working it out with your static; it is not something people should be using as a guideline to demand that others play by their rules.
