They could've done so much more with this. And if it ended up being a caster with blue mage flavor only, how is that different from essentially any dps? They're all variations of the same role doing mostly the same thing with utilities being the bigger difference. Red Mage wasn't exactly what we wanted but they made it work within the battle system of this game but Blue Mage was too hard for them. What a waste of interesting new abilities and spells that won't be used in meaningful content anytime soon if at all.
