You're not really addressing the real problem with the fairies. The real problem is that Eos's healing is far and above any support that Selene brings. Even with your proposed changes, that's likely not going to change. Heck, you even got rid of the one thing people use Selene for now. Strong single target healing isn't going to make Selene better since the SCH already has pretty decent single target healing in a semi-spammable Lustrate. Selene's support has to be far-and-above any sort of healing Eos can bring in order to make Selene worth it, but then we have the problem that Selene becomes too good and Eos is just for these specific parts. This is why I'm saying the fairies should be completely redesigned as regen and shield focused (to act like both stances and pets). This removes the problem of one pet being relatively useless (they both have their uses depending on fight and co-healer).

I'm still of the mind that Dissipation should be a free fairy switch. Nothing else is really needed (though with the change to Summon, this may not be necessary). (I am also still of the mind that the Fairy gauge should be like Kenki for the fairy cooldowns.)
