Here's the thing... I'm not telling anyone to quit the game or to gatekeep the game when I say things like "if you want WoW healing, then play WoW." (Or if it's more applicable, perhaps Ragnarok or another MMO that better supports triage-focused healing), my point is simply, if you're really frustrated with the idea of healers having DPS rotations, the lack of damage taken in most if not all forms of content, how healing has been moved toward OGCD weaving between DPS spells mostly with very little requirement to use GCD heals, then FFXIV is not satisfying you or providing the experience you're looking for.
If what you want is to play as a healer who doesn't attack and focuses the vast majority of their attention on healing, then would you not be happier playing a game that supports that? That's not saying you can't come to FFXIV to play through the new story, do new sidequests, chat with your friends, do other forms of content like the upcoming deep dungeon, treasure map hunting, etc. But if you're raiding in FFXIV, and this game's combat medic formula is not fun for you, then maybe you should raid in a game that offers healer gameplay that would better satisfy you. This may not apply to everyone, but I'm just trying to point out the FFXIV is not the only MMO, and if the gameplay is in one way or another putting you off, and there aren't any other jobs that are fun for you, then looking at other games is an option for you and may be the solution.
I like fighting games, and I really like the characters and style of King of Fighters, but I hate how King of Fighters relies so heavily on quarter-turn and half-turn input for combos. So While I might play King of Fighters very lightly and faff around, I much prefer the gameplay of Tekken even if I'm not as big of a fan of its cast. I can still find characters I enjoy, and the combo system feels so much more comfortable, and that's what I play with one of my friends when we get competitive with one another. That's what I'm talking about.
That said, I've said many MANY times before that I would love to have a healer reworked in a way where their DPS contributions are largely filtered through your teammates to create the illusion of a support-oriented healer in an attempt to give players that want heal-focused healing something that at least treads a line they may better enjoy than having to directly cast offensive spells for 80% to 100% of their GCD and still can compliment the encounter design of this game. I am all about trying to create different playstyles that can appeal to different types of players, but I don't know if FFXIV's design team will ever be willing to do that despite how beneficial it would be. I do think they will eventually hit a wall where healer design where they can't just keep adding healing buttons and will be forced to respond to the increasingly prominent criticism of healers that has started to bubble onto major content creator discussions. I can't speak to how ambitious they will be with how they respond, but the ship has leaks, and they can't keep ignoring them forever.
