Next healer class released should be

[MirronTulaxia]

Oh, that's why I missed it, you didn't reply with a quote.

Using water, wind, and earth aether does not mean "blasts enemies with these spells offensively". So all of your evidence falls to the wayside in that sense. None of what I said was "they won't use those elements". But there are a lot, lot more ways to use those elements than chucking them at enemies. Scholar uses them without doing that after all, as does White Mage, likely Astrologian too. So even if we got Geomancer as a healer it wouldn't have to somehow be fire/ice/lightning aether only.

There also isn't an Astral or Umbral focused Caster, and those are just as important (if not more really) than Wind/Water/Earth. Which really makes it difficult to justify it on the basis of completing things, as you're only making the obvious two missing more of a thing as opposed to where we are currently.

Snip.

Oh, I definitely wasn't saying robes as a deterrent. I'm just making the point that whatever we get for Chemist is not going to somehow be radically different from the existing healers. It'll be a DoM, it'll use a melee weapon, it'll likely have something resembling robes or maybe a light armor outfit (aka Scholar, which really is a good thing to look at when people think Chemist), it'll have cast times and MP costs, so on and so forth. People think it's going to be something resembling... I don't know, Sharla from Xenoblade or some such, and that's a relatively tame interpretation to me of the things people seem to push for.

Snip.

The issue with this is that Gunbreaker and Machinist already do this, and that makes them DoW. While it's certainly possible you could get some clunky tech-like array and you have to channel aether into it for all of your actions it seems like a needlessly complicated way to do it. Just... you know, make it an actual caster. Trying to jump through a bunch of silly hoops when Alchemist already exists, from the Ivalice games that XIV loves to copy, seems a lot simpler. Just change the name to one of the other terms (in Japanese there are two they use for Alchemist, so whatever one they currently have for the DoH can be ignored and they can use the other) and come up with some fluffy silly translation for it in English/other languages (sadly there isn't really a lot of good Alchemist substitutes).

Can I hold you to that?

You can hold me to that. If we get a Chemist that does all the things I listed? I'll be quite fine with it. But I can already guarantee we won't. It's just people trying to fit a square peg in a round hole, or going wild with fantasies. Being able to be pragmatic and realistic is better than falling for forlorn hope.
