Something relevant to this: Back in ARR 2.0 and 2.1, the healing experience in PUG dungeons was very different when dealing with a scholar versus a white mage. Back at that time, scholar became a hybrid dps/healer due to branching out from the arcanist DPS class. To balance that, it's "cure II" level ability was limited to 3 charges (lustrate). The dynamics between a party with a white mage were different than one with a scholar. A white mage could carry a mediocre party doing wall to wall pulls due to being able to spam cure II if DPS was too slow or the tank didn't have enough mitigation. Scholar was only enough to wall to wall pull if every single person was at the top of their game because their big heals used aetherflow stacks. If everything went right, it was potentially faster than using a white mage due to their dot spam. If things went wrong, the tank would get eaten despite spamming adloq because of how the shield consumption vs cast time worked. The devs pretty much said they didn't like that approach, so they stripped it of DPS abilities and replaced them with more healing abilities to make the healing more "safe." That has pretty much been the philosophy going forward, and if my memory is accurate, the stuff in dungeons today hit lighter comparatively to mobs back in 2.X.

I'd like to know what the dev team's philosophy is on healers today. It looks like they've compartmentalized job abilities with sage in a way we haven't seen in previous expansions.
