My OCD likes there being a Black Mage DPS, a White Mage healer, and Red Mage tank. Also the kind of sort of Red Mage from FF Type-0 had duel foils true, and its not like they dont take liberty in this game but.... I think I like the idea of a single rapier/saber and a free hand to cast with. As for tank armor, most jobs dont have their classic look until the mid-40s anyway. Just make the AF gear sexy. They sort of hinted at this already being a thing.

The tank coat from the library is red.
