I just had an enlightenment regarding Healers in Shadowbringers

[Deceptus]

As for the Fairy, a few adjustments had to be done so that pet jobs weren't so difficult to play for the newer players, but not so infuriating when you try to queue something and they just...cast whatever they're doing, and then do what you ask them to. The fixes to the summons and their casts being Instant helped alleviate A LOT of issues that the Pet System had in its previous iterations, however not a lot of people are happy to see Selene basically be a "skin" for Eos.

In my opinion, I want to think that the developers were having a difficult time creating unique decisions between Eos and Selene, given the fact that Selene's kit wasn't even close to competitive with Eos while also not overpowering the Fairy to where it was in Heavensward; this way, people can have both Eos and Selene which are tied into SCH's storyline and open up their options in both adjusting SCH's contributions and the Fairy's contributions.

In this regard the developers took absolutely, 100% the laziest way out they could.

Instead of balancing the two fairies and giving them more of an identity (Selene the buff or debuff fairy?) They just made her a reskin of Eos.

That would be like telling Summoners, "Well, Titan is useless now so it's going to be a reskin of Ifrit. You get a melee pet and a ranged pet in Garuda. Hope you like it!"
