I definitely want them to have their own identities again, though I think there are some issues with old Selene. As a Dancer, for example, I'd much prefer you didn't give me Fey Wind. I don't want any Skill Speed because it could hurt my rotation, which is a pretty big issue with Skill Speed in general for almost every job (BLM being a notable exclusion to the rule). I do think there are things about the old Selene that would need to be changed.

Something I had in mind was making it so that you actually want to swap between Selene and Eos mid-battle frequently. First, make Summon Eos and Summon Selene Abilities rather than spells, instant cast, and with a 15 second recast, then, their main tools could be like this:

Eos
- Embrace: 250 Potency, 2.5 seconds cast time, and make it cost 5 Faerie Gauge
- Fey Blessing: 400 Potency, instant cast, and make it cost 20 Faerie Gauge
- Fey Illumination: No major change

Selene
- Fey Spark: 4 second Stun, 2.5 seconds cast time, and it adds 5 to the Faerie Gauge
- Fey Tricks: Bane effect when you target enemies and Fey Caress effect when you target allies, and it costs 20 Faerie Gauge
- Dusk Glow: Restores your MP

The idea here would be if SCH could get some new DPS tools that are high DPS but also high MP costs, and Selene's support is about batterying your MP to allow for those powerful DPS spells. Meanwhile, she can't actually heal, but can build your Faerie Gauge for you for when you need to swap to Eos for healing, and also being good for starting big pulls.

I'd also like to change Dissipation into something that swaps Selene and Eos and grants you 50 Faerie Gauge for when you need Eos' healing.

Also, can we return the ability to manually cast Embrace? I don't really understand why we got rid of it when auto casting was always an option to begin with. Let the people who want to micromanage her do that. Just make the auto casting command apply to only Embrace so that it works the way it does now.
