I feel like all of you have forgotten the major struggle of trying to heal up a group taking large amounts of AoE damage, in which the other healer may have died/disconnected/thrown off the edge or simply out of mana. Emergency Tactics gives scholars an amazing skill to use in EMERGENCIES. (It's even in the skill name, people) Yes, in normal situations you won't need it, but omg huge damage coming and you cant keep up? Emergency tactics for a giant heal. Just think back to Titan Extreme and all of those stomps with your White Mage partner off the edge/dead. Scholars literally had the WORST time with that. If something similar were to ever come up again I'm sure all of you would be praising SE for this amazing skill.
The one skill I would change is Dissipation. Change the potency to 30% to match with White Mage's Divine Seal, and allow you to summon the OTHER fairy at not cost (maybe instant cast?) while the one you sacrificed is on CD.
