I think the developers really need to take a step back and take a look at healing, and by proxy, tanking. Even if we look past Savage, why is the only significant damage done during trash to a tank? Why not have enemies that blanket the party with damage? You can talk about dungeons not being difficult, the player base not being good enough, or whatever else, but those are just bad justifications to keep healers in a sorry state.

More consistent damage is something that should really be talked about. It's gotten to the point now that healers will actively whine about having to do their job, heal, if they have to cast a GCD to do so. If you asked me, if a healer/healers are not regularly casting GCD heals, your content is not well designed.

Ignoring the healing aspect here for a moment, why exactly is a job that spends more time DPSing than they do healing only doing so with one button? DPS as a healer should be something you squeeze in while healing - healing shouldn't be what you squeeze in during DPS. Maybe instead of so many % dmg reduction skills healers should never have been given in the first place they could've been given those buttons to provide some semblance of a most simple rotation.
