It's really not Fey Wind, but rather Selene choice as a whole that should be re-evaluated.

All the good Scholars start end-game fights with Selene, press Fey Wind, and re-summon Eos before the countdown is over. Don't need Fey Illumination cool down at the beginning, so trade it for Fey Wind.

It worked fine in Midas Savage. A6S and A8S had mandatory boss silences.
