How could you do this to AST?

[Ceasaria]

I dunno, I think we have enough experience and info, at this point, to see that their design philosophy isn't changing, so the decision to make another "pure healer" is extremely worrisome.

Hmm, for Shadowbringers all healers followed the principle of Pure Healer.
Now they want to come back to two groups of healers as it was in ARR which is really good .
And like Hyomin Park says, Pure is for Regen (and/or strong raw healing maybe).

This. Since it's inception, AST has been a nightmare to balance because of it's dual nature.

Yeah and it's what we already asked end of Stormblood, delete that Noct Ast and make two groups of healers.
Glad, they have adopted that choice.
