People need to remember that Chemist could also end up as a Ranged DPS and not assume it's a healer. Same thing happened with dancer and look what happened.

Personally, I'm unsure if Chemist will come. Sure in HW it was thought of as a potential item healer but then AST won out, but similarly it's possible that the way Chemist is envisioned by the devs will not be possible in this game as is. It might end up as a limited job like BLU.

Also want to make sure people do understand that if somehow Chemist does arrive as a healer, it won't be any different than the other healers like other people have mentioned. It never will be after the homogenization that was, rightfully, necessary to further add healing and tanking jobs.
