Don't forget the Ronkan (I think?) gear from ShB. It's chianmail, which is very much metal.
Do you?
Or is this just your heresay again?
You made a claim first. Can you prove it?
ShB was when just about every Healer felt comfortable DPSing...because the DPSing was so streamlined that it was almost down to "if no healing is needed, press this button over and over until healing is needed". This is when midcore content and even casual content adopted the policy, as well as Extremes and even Experts, and it was the expectation across all levels of endgame content, not just Savages. Note that "Endgame" does not mean "Savages", it also includes Expert roulette and Extremes.
Hammer -> Nail's Head
This is the reality of our situation.
Too much power creep, too many overpowered oGCDs reducing the need to GCD heal, encounters designed to be mitigation checks rather than healing on unavoidable damage AND for avoidable damage to outright kill most players so that healing to make up for mistakes often isn't possible, and in more casual content (and some hardcore content, like the Ultimate TOP that was 0 healer cleared) Tanks and DPSers having too much healing as well. (Look at how much healing DNC can output sometime; it's insane and makes 4 man fights trivial to clear without a Healer, and obviously I don't need to explain WAR at this point, right?)
Not to put too fine a point on it: But this will always be true from highly skilled players doing casual content.
"But not DPSers!"
...yes, DPSers, too. A lot of high end players get bored doing AOEspam wall-to-wall pulls and see Experts as a chore to DPS, too. And for people used to doing DPS rotations while avoiding complex mechanics in the Savage dance, doing an optimal DPS rotation during one-mechanic-every-60-second octopus at the end of Aetherfont is "bored to death", too. Same for Tanks. There's nothing unique to Healers about that.
If high end content engages you, that's what you're going to be doing more of, and with the advent of Criterion, they don't need to change-up "casual" content to be "not boring" for high end players if you have valid alternatives to grind for tomes/etc.
To put it simply, you likely CANNOT design content that is non-trivial/non-boring for high end players to do over and over and over again that ALSO is still accessible for normal players in a general environment. And this community has generally accepted that MSQ is for everyone, not just hardcore people, who tend to only do it once before moving on to content more engaging to them. (Note Expert roulette is MSQ content, thus is MSQ). At the end of the day, some content is just going to be boring for you if you're a hardcore raider. That really can't be helped. The goal should be to make it where such players don't need to keep doing the content (most everyone's fine with the one run for the story, but not the weekly grind for tomes) and can get their tomes from content they find more enjoyable.
Honestly, Criterion is an interesting design choice going forward since it has both solo, casual, and hardcore versions. It just needs to provide tomes commensurate to that.
I don't think it does, it's a different argument.
Think about it - how in-depth would a healer rotation in Lapis Manalis have to be for you not to be bored? Would a 1-2-3 not still be boring? (As noted in that ongoing discussion in the Healer forum right now, everyone seems to agree that wouldn't do it). What about a SMN rotation? No, that gets called boring all the time as well. So it would have to be a full on DPSer rotation before "more DPS buttons" would really fix the problem. Dia having a Thundercloud proc would be novel for...a week. A 1-2-3 Stone-Aero-Water combo would be boring overnight.
I think the issue is that nothing WOULD actually make 4 man casual content NOT boring for high end players such as yourself or others like you, unless we get something either high APM like GNB or DPSer level difficult like BLM. And at that point, we run into all the attendant issues of Healers having full on DPS rotations.
Moreover, an additional issue:
UNLESS the damage gap between optimal and "glarespammer" is small, then when you get a Healer that does the bare minimum, now you're extending the time the run takes to the point of really annoying regular people, and we run into people just dropping healers and doing 1T/3D premades (even more than they do now). Meaning people's "get in, get out" runs will take even longer, leading to even...more...complaints.
Also:
More or less, this.
This, and that we're so oGCD healing focused, it leaves us with a LOT of "dead" GCDs to fill, so we fill them with the same damage nuke spam. If all oGCD heals were GCD heals (or, at least, a lot more of them were), that would change that a lot. WHM right now has the least oGCD healing and the least Glarespam (ironic, given the name) of all the Healers.
