Something I’d add is that the disparity between Selene and Eos never felt great, not that I agree with removing that entirely, but while Eos’ tools all felt appropriate for her identity, Selene was two almost completely useless buttons and one party buff that essentially made her objectively better for that reason only. Eos was like the training wheels, and once you could manage the healing without her, you’d rely explicitly on Selene.
It’s been mentioned before that attack speed is not a good buff because several jobs do not want it and even those that do are setting themselves to a specific skill/spell speed anyway
I’m more interested in seeing SGE’s tools at this point, but I do hope Selene one day gives something different to Eos again, just it’d have to be something different to what she had in the past. Personally I think Selene should hold additional mitigation and utility while Eos is more raw healing. That way your faerie can also compliment your co-healer as well. Selene fits with a WHM who has plenty of burst healing, but Eos pairs better with SGE who already has a ton of mitigation.
