Confirmation bias. Whispering Dawn is used the moment at least 1 person dips below 90% HP. Similarly, Embrace is triggered when anyone dips below 80% HP.

A fairy set with Place auto-heals marginally faster (rather, there is slightly less delay after finishing a cast before starting the next). Manual Embrace is far from necessary but it is helpful for difficult content when you don't want her to wait until after a particular hit to start healing. Beyond that I don't personally do much micro-management, but that's partially because I feel Eos is pointless for most fights.
