SCH is more about mitigating damage as opposed to big heals.Â
MP Things:
USE ENERGY DRAIN! Seriously. If your aetherflow cooldown is done, or will be done and the party's in good condition, spam it a few times and get some MP back, and aetherflow to boost it up more. If you're having to repeatedly throw adloqiums on the entire party, there's an issue.Â
Use physick more often than Adloqium. Or Succor the entire party if you just need a little bit of healing. Physick uses less MP, and heals slightly more iirc. I use a ratio of about 1 adlo to 3 physicks, unless it's a  big pull and the adlo is getting wiped out fast. (Which in that case, it's up to the DPS and tank)
Keeping up Galvanize:
Only keep it up when needed. If you're fighting a boss, probably only the tank needs it. Just like a WHM wouldn't keep regen on the entire party at all times, you don't need to keep galvanize on everyone either. If you've got stoneskin, you could layer that on top as well.
Aurum Vale healing:
This is a little harder to help out with without seeing how your tank pulled and how you healed. A lot of the stuff in AV hits pretty hard, so if your tank was overpulling for the group's ability, chances are you were getting overworked. Especially if people couldn't dodge. If there's an AOE-safe spot, you can also stick Eos near the tank or DPS. A quick succor on the party before pulls can help. In somewhere like AV, where you're level synced or at-level, it's a lot harder to accommodate people who are not as ready for the dungeon as they'd like to be. It's also a lot of dodging.
