Just to set the record straight, the threshold is 80% for self, Eos, or party members. If you are below 80%, she will heal you regardless of everyone else's percentage. If you are above 80%, she will heal the lowest % party member in range (which btw is only 21y for auto casting last I tested it).
I personally think it works well as is. Honestly, it was a much bigger deal at level 50. They nerfed off about 1/3 of your faerie's healing potency with level scaling formula to 60 so Embrace is equivalent to 200 instead of 300 at 60.
