For me Red Mage has to be something like Cabal`s Force Blader or L2 Blade Dancer. A Support/DPS which ranged and melee attack combos, like, a pumped up Dragoon but instead of jumping back and forth, dashing, casting a few "bolts" from range then triggering a "dash" landing a few "slashes" and then triggering another dash, to literaly, rinse and repeat. And after each successful combo he triggers some passive buff to the party.
