Additional rework ideas for some SCH skills:

Summon Eos/Selene: Remove these abilities and tie Lily to our job stone so that when we choose SCH or are revived from death our Faerie is instantly called with us. Replace Summon Eos/Selene with a "Conversion" type skill that would change Lily from one form to the other, also changing some of her abilities. (Essentially, turn the faeries into different "stances.")

Emergency Tactics: Rework into a 15y radius oGCD that consumes Galvanize, Catalyze, and Seraph Veil and converts them into health. This would allow SCH to keep a lot of their shield healer identity and give them some potential burst healing when shields aren't necessary.

Dissipation/Summon Seraph: I like the idea of combining these skills. Instead of just eating your Faerie and locking you out of your faerie skills, you replace her with Seraph and gain some Aether stacks. Could also be combined with my original idea in the OP and turned into the "burst damage" window for SCH, or maybe just a Dreadwyrm Trance/Lightspeed style mobility tool.

Whispering Dawn/Fey Illumination: Keep the base abilities, but also give them a bonus depending on whether Eos, Selene, or Seraph is out. Eos Whispering Dawn grants a burst of healing and then a regen, Selene applies a regen and debuffs enemies in range, Seraph gives the regen plus damage mitigation. Fey Illumination for keeps the 5% magic damage mitigation, but Eos keeps the extra heals, Selene gets extra shields, and Seraph applies both.

Fey Union/Aetherpact/Faerie Gauge: Maybe more than any other skill in our kit, these need a big rework to feel impactful. Following my previous suggestions Eos and Selene would apply different effects based on which "stance" you're in, but I'm at a loss as to how to differentiate them. Seraph should be able to use a version of these skills as well, but perhaps her version of Aetherpact would be instant instead of channeled so she's not animation locked during her summon time. A DPS ability tied to Faerie Gauge would also feel much better.

Just some ideas I had while playing the other day.
