Y'all people arguing for BLU to become normal are missing the entire point of BLU. They could standardize it for regular play, yes, but they already said years ago that they would not be willing to sacrifice what is quintessential to BLU to do that. Of course, they could do that. Of course, it would make a lot of people happy. It's not what they want to do with the job though, due to the nature of this MMO.

Also, Aetherial Mimicry isn't a sign that it's being more standardized. There's a clearly more powerful than the others option there, and it's Healer Mimicry. Like, sure the DPS one has more DPS due to the Crit/Direct rate+ and the Tank one gives x4 to defenses as well as buffing cooldown related skill, but due to Diamondback and other things, Healer Mimicry is just way more potent than the other two options. It's a skill that was added to give BLU more power overall without basically giving it god mode. Imagine if all three could be active at once.

It's best like it is now, living up to how it works in all other Final Fantasies, with its class fantasy and lore intact, not breaking the game in anyway(though it did flirt with it during Yokai) while being an enormous amount of fun with a ginormous skill ceiling. You normalize it, you kill it. You're just asking for BLU flavored caster. That's it. You're not asking for actual BLU. And that's a dreadfully dull thing to ask for.
