What I've tended to do (only level 40 here, so this probably doesn't work out well at 50) is I'll pretty much for Eos to cast Embrace on the tank between every action I make. So Eos is pretty much healing the tank, while I heal up party members, unless the tank is tanking too much damage and then I'll only heal the tank.

So far, the only thing I think needs to happen to the scholar class, is for the faeries to only cast Embrace while in Steady. That way I can control when Whispering Dawn gets used. If I could use that during the AoE phases, things would be a lot better, but its generally on cooldown. I tried setting up keyboard macros to make it so that I would cast Embrace, the immediately Steady, followed by Obey, but it seems like half the time that doesn't work and she still casts Whispering Dawn when I don't want her to.
