Here is what I'd change:

Eos
- changing Fey Covenant from "increases magic defense by 20%" to "increase defense by 10%" ( not all mobs deal magic damage )

Selene
- change Silent Dusk to a +5% slow aoe skill ( stacking with shadowflare )
- reduce caress cooldown to 40-35 seconds
- empower Fey Wind to 5%

Both
- empower embrace from a 250 heal potency skill to a 300-350 one ( physick has a 400 heal potency and we know how "not so useful" it is endgame wise , fairies now heal for about 3 k hp , physick for 8 k....tanks have about 45+ k hp , healers have about 35...a 3 k heal , even though it can be added to your main spell, is not useful and the addition feels unpractical ).
