Long post follows, tl;dr after.
After queuing with my wife as 2 (lvl 36) Summoners for over half an hour for Titan storyline fight, I decided to switch to Scholar. I had only main healed one instance before, Blayfox Longstop, with no issues, though HPs ran a little low on last boss. Sure enough, after I switched and reloaded DF we were instantly grouped up and in.
Straight away, I fast-cast healing Fairy, activated aetherflow for the two charges, cast protect and targetted the tank.
I knew it was a primal and was prepared for the tank (who did his job admirably, never lost hate) to take a lot of damage, particularly as he was a Warrior. I was not prepared for the amount of damage I had to heal on everyone else. I often found myself scrabbling to get everyone healed while keeping the tank out of red hp. MP wasn't much of an issue, aetherflow and energy drain kept me topped up. Time was the issue.
I felt like whenever I had to cast Physick (and whatever the SCH-specific heal is called) on more than one other party member, I would flick back to the tank as his HP dipped under half andd by the time my next heal hit him, he would have taken at least another hit.
This created problems when someone was entombed in stone or when Titan's heart popped. The only nukes I felt I could cast safely were Energy Drains for their instant cast and the very occasional Bio II when everyone was ok. I feel I should have been contributing more to DPS as we wiped to Earthen Fury more than once, but I felt constrained by needing to constantly concentrate on the tank's HP.
Healing Fairy's AOE regen was a godsend, allowing me more time to nuke occasionally, but not something I could rely on. I never switched to buff fairy, was that a mistake?
I also had not done the SCH 35 Quest which I see gives an AOE regen and minor stoneskin, would this have solved all my problems and made the runs a lot smoother?
tl;dr - What hints and tips have you discovered for either SCH healing in general or the Titan fight specifically that would help a reluctant main healer?
