Your Stance on Cleric Stance

Yeah, the problem is the "healer chose healing". The game is not designed for that. Healer is a terrible name for a healing DPS. Which is what they're really designed to be.
A "healer who chose healing" has a right to not like that the character is a healer DPS and be mad at the designers, but to not play half their class (as in the ice mage example) is bad. Just as bad as the ice mage.

Except they're not designed as "healing DPS". If that was the case they'd have varied and interesting DPS tools, not 2 DoTs and single nuke.

Look at Black Mage. They have their fire spells, ice spells and the respective astral/umbral modes that they need to switch back and forth between while up-keeping enoch, managing thundercloud procs, knowing where to drop their ley lines and so on. They've got this fully fleshed out kit and interesting kit for doing DPS.
Contrast WHM and particularly AST. They've got a few dots and a boring nuke. No interaction, nothing to manage. SCH approaches having something of DPS toolkit considering their Arcanist roots but even theirs is kind of flat and flaccid since every single job ability the get sans broil is a heal or support ability.

These designs scream up and down that DPSing is a distant secondary function. Nothing about how the game presents the classes, itemizes the gear or assembles parties implies that they're meant to be "healing dps". The whole paradigm seems to be a meta that has cropped up entirely out of the fact that monsters are effectively wielding feather dusters.
