the first thing is you do Not need or should keep ANYONE at full hp at all times (unless youre doing some savage fights, but this is baelsars). Scholar has a fairy that slowly but steadily heals people up, and people are rarely ever taking constant damage so try to leave more work to the fairy. This isn't limited to embrace, try to use succor less and whispering dawn more, its not only more powerful (700 potency vs 300) but also completely mp free.

if you need to spam heals on tank you can rouse the fairy and use whispering dawn to get a strong regen on them, you also have fey illumination and largesse. try doing adlo and > physick or adlo> emergency adlo if the tank is really hurting bad and youre out of aetherflow stacks for lustrates.
