A few things I want to address, starting with the last:
The smiley face was to convey humor, not snark, which is why I even clarified in the parenthesis. I'll try to refrain from humor going forward, since it's too easily confused. You have remained largely neutral in tone. Though you might not have read it, I specifically pointed to you as a sober minded, reasonable, and respectful individual in my reply to T-Owl. Had I meant it as harsh and biting, there'd be no smiley face nor the parenthetical. But, as that was confused, I will try to refrain from doing so again. Though I would note...eh...maybe best not.
To the top: I again am a bit confused. If you said what someone is describing they want to play sounds like a Tank, should they take offense to that? If someone likes seeing big damage numbers, but also said they want to draw the boss's agro, shrug off attacks, manage a suite of defensive abilities to survive hits and protect their allies, but wanted to do this on a Ranged Physical, should they take offense if you said "What you describe sounds like you might enjoy playing a Tank"?
Though I would like to ask, and no snark or sarcasm: What do you find satisfying about DNC's gameplay loop? I haven't done basically anything with DNC, so I'm curious what it has going for it that you find engaging? And are there other "simple" Jobs (for example, if you play and enjoy SMN or WAR) that you like (if any) that you could describe what in their gameplay loops you find engaging and satisfying (if you do - if you don't, feel free to just say...well, that you don't?)
"further develop" - no, made different/distinct. I don't consider those gameplay forms better or more developed. As you know, I hate DoT gameplay, so I would NEVER describe SCH going back to the SB kit to be "more developed" or preferable to me personally. I just think it would make OTHER PEOPLE happier, and I'd like those other people who do want to play healer but want to play that kind of healer to have one in this game they can get on, play, and be happy with. I've asked you before why you're so adamant that I and those like me not be given the same offer, and as I can tell, your answer is generally "you deserve better", but when I press with "what if we don't WANT your better?", there's really not a great counter to that. Indeed, your "if you do not want that...you are playing the wrong game" could be seen as a bit...dismissive? Animosity? Harsh?
I'm certain you don't intend it to be harsh, but it comes across as a brief, harsh comment. To apply your descriptors to it. (And not with snark - it seems to me harsh whenever anyone says to another person they are unwelcome in a given venue, including games, even if it was not intended to be so)
To answer your question: "but then why are you playing FFXIV to begin with?"
Remember I've been playing since 2.3. The game WAS designed for people who want to engage with GCD healing and not with GCD combat at the time for WHM players. And since that time, I've met people, enjoyed the story, the characters, the world, and the content. I love exploration stuff like Eureka and Bozja, I love challenging stuff like Extremes, I love trying to collect mounts and minions and orchestration rolls, to challenge myself with various forms of content, and to play with friends. I also have long thought - challenged of late, but I still hold it as true - that FFXIV has one of the nicer, friendlier, more caring and welcoming communities across MMOs.
Those things are all why I play FFXIV. Should I, loving those things, coming to the game when it DID accommodate old-school GCD healers, suddenly abandon the game because some people on an internet forum have told me it's no longer designed to play that way even though the Devs are clearly trying to keep it that way for WHM by the very design it has today with the Lily system?
