I agree with the sentiment that you don't get how good scholar really is then. If the fairy isn't healing a lot it's usually because they don't have a target that the AI wants to heal. In which case I'd say you need to be more patient and hold off on adlo/physick spam, place it closer to the tanks but not in cleave range, and trust that it'll heal people over time. The only thing I struggle with on Scholar is running out of back to back AoE healing options, which literally only happens if the other healer is dead and I go through a priority list of Succor (if I know the shield is needed) into Indom/Deploy/ET depending on context, and alternate between those options till all I have left is reshielding a Succor. By the point all of those are on cooldown at once the raid is either dead or over the hurdle and you can Whispering Dawn and/or Rouse and start focusing on Raises while Indom and ET cool down for the next sequence of mechanics.
