I hate to, but I think I put down healing for now. Please make it engaging again, SE.

Comparing DPS rotation vs Broil/Biolysis in any of the contexts he mentioned completely ignores the healing part of playing healer.

This shows me that you're all hyper-aware of your Broil/Biolysis, so much that you forget that healing is still a significant part you have to think about.

You know who else completely ignores the healing part of playing healer? Square.

Through constant oGCD inflation, Square has dumbed down healing significantly. They have also dumbed down healer DPS kits significantly by removing skills. The combination of the two results in a very dumbed-down role. Playing a healer in FF14 is playing the game on easy mode. As your rotation consists of "press 1 until the boss dies," the only thing you have to pay attention to are the fight mechanics, and that's just a matter of scripting your oGCD usage to match the scripted boss damage.

The "healing part" of playing healer is occasionally weaving an oGCD heal in between two casts of Glare/Broil/Malefic. That's it. If the rest of your party isn't huffing glue, you have very little reason to touch your GCD heals (except maybe to refresh a regen). Roughly 70-80% of your GCDs are spent spamming Glare/Broil/Malefic. Why is this state of affairs acceptable for healers, but not for tanks?

Tanks, like healers, have all their tanking functionality off the GCD. Defensive cooldowns are analogous to healer oGCDs. Yet tanks all have proper DPS rotations, while healers don't. Why don't we get anything interesting to occupy the significant downtime when we're not required to heal?

Healing is unique in its own way, because it's the collective effort of two healers. Meanwhile, playing DPS is a predominantly individual pursuit.

And DPS is the collective effort of five players, is it not? DPS openers are designed the way they are specifically to maximize synergy and synchronize raid buffs. Yet DPSers have complex rotations.

Tanking is also the collective effort of two or more tanks. The MT and OT have to coordinate to handle tank swaps, adds, and shared tankbusters. Yet tanks have complex rotations.

Healing, as mentioned before in posts you seem to have missed, can be done solo, because healers are so powerful. And yet, healers do not have any rotation at all, much less a complex one.
