Actually, I do think they should be reworked from the ground up, and specifically, they need to have a combat designer that understands how healing currently works in Final Fantasy XIV sit down, establish several points, and rebuilt each healer with a more defined focus on how they go about healing. Right now, all healers functionally heal with the same core methodology: Survive off OGCDs as much as possible to allow for as much DPS uptime as possible. Here are the points that I think need to be recognized:

1. What is each healer's core identity, and what defines how they approach healing and how they approach DPS.
2. We need to stop pretending that RDPS isn't a core responsibility to healing, and doing so only hurts the enjoyment of healing for many players. We can also design RDPS contribution to be approach differently to appeal to different playstyles, including ones for players that want to DPS less and support more.
3. Trim the fat on the widespread accessibility of Regens and Shields as they are kind of everywhere and what they do is essentially allow for significantly more DPS uptime.

For White Mage, what I think should be established is:
- An emphasis on equal balance of healing and direct DPSing where healing fuels DPS and DPS fuels healing. We currently already see this to some degree with the lily system and it should be expanded upon.
- Trim their usage of Regens and Shields and make them more focused on high potency healing largely through GCD healing.

For Scholar, what I think should be established is:
- Restore them to being the main DPS healer by giving them a more engaging direct DPS kit and not only retain the current mentality of OGCD priority, but strengthen that interaction by developing their resource management system to make it so that skilled players can generate more OGCD heals to maintain longer DPS windows.
- Trim their usage of Regens and emphasize their usage of Shields in ways that can be utilized to extend DPS windows by turning them into OGCD actions.
- Restore identity to both Selene and Eos in a way that doesn't make one superior to the other.

For Astrologian, what I think should be established is:
- Emphasize their identity as the support healer by giving them the ability to augment party DPS through GCD buffs instead of OGCD buffs, so instead of Malefic spamming, they are instead spending more time buffing allies.
- Trim their usage of Shields and redefine how their sect system should work. Give them opportunistic Regens and delayed healing effects to compliment their "time mage" elements.
- Rework their Cards once more in a way that retains their consistency, but also restores their lore and unique functionality in a way that feels controllable.

Healer 4 should focus on adopting a system different to what we have now. There are many options they can go in, such as a predominantly ground targeting healer, a drain healer, or perhaps a healer who's RDPS contribution is largely OGCD based.
