Remove the GCD cost from on-demand healing.

[Sloprano]

GCD healing then. Spells with an MP cost. Always available, no timers or gauge requirement. Always there. On Demand.

If I get you correctly, then it's tossing off the reigns of cooldowns and make us stand around a cast a bit more, and more varied, and not just always have a cooldown for everything.

In case you haven't seen it, I would recommend taking a trip down revision history for the Arcanist and Scholar wiki entries for 2016. Where we had what you are describing: Spells on mp cost. Always available, no timers or gauges. Always there.

Bio, Bio 2, Miasma, Miasma 2, Aero? No cooldown, only gcd.
Bane? 10 seconds.
Shadowflare? 3s cast, no cooldown.
Cleric stance? 5s cooldown when you enter it.
Physick, Adlo, Succor? Either weak and cheap, or powerful and expensive. Always there.
Pet hotbar? Embrace usable all the time every time.
Sustain? 1s cast, gcd.
Ruin and ruin 2? Your boilerplate or Blind-inducer.

Just those above? Those couple skills with barely any cooldown, but gave you something to ALWAYS have something to do? It made the job.

What cooldows there were not even that long:
Virus? 1 min.
Aetherflow? 1 min
Rouse? 90s
E4E? 180s.

Then we enter Heavensward and you can see SE start experimenting with oGCD cooldowns and Broil substance abuse:
Indom, Deployment tactics, Emergency Tactics, Dissipation. Four out of five new spells were oGCDs.

But that wasn't a problem: because we already had spells that cost no mp, always available, no timers or gauge requirements. So cooldowns enhanced the job. I remember every single GCD and Aetherflow I wanted to press was at odds: Can Embrace cover it or do I need to Adlo instead of refreshing a dot? How long until I need the next shield? There are 30s until Aetherflow refresh, I have one stack left, do I wanna chance it on Bane or should I keep one for Lustrate?

But now cooldowns IS the job.

Irony aside, healers who dont want to dps will just continue to do so even if all healing skills becomes ogcds. Instead of yelling at them for being afk between two cure 1 gcds, you will yell at them for being afk between two cure 1 ogcds XD

It really brings the old adage "Netflix healers" to mind. Not just because they could get away with it, but because it was such low effort and so boring one COULD finish an entire movie or half a season of Dark when doing your daily routine.

That neither the application of healing, with hypothetical fun and rewarding unique job mechanices, or the act of doing damage, with imaginary amusing and captivating exclusive features on the job, is in place when repeating the exact same steps then boredom will set in. And it is when we get bored we find ways to entertain ourselves so time goes faster. Entertain ourselves when playing a piece of entertainment.
