Unfortunately I feel that if Chemist ever reaches XIV it'll be as a physical ranged DPS, because of the whole "can't think of it as as Healer, because Casters". Mix between Dancer and Ninja. They'd use a hand-cannon like FFTA2 Cannoneers and their thing would be that their big "Ninjutsu/Step" CD would be Mix where they input several ingredients in the cannon and release them as a "mist" buffing the party or debuffing the enemies.
