But yet my RDM does have the ability to focus on casting from a distance (or up close)... so I'm not sure what exactly your concern is. If it is that it doesn't gain the use of nukes or cures naturally and only through cross class abilities then I have to present PLD as a counter to your argument. Historically PLD has always received white magic natively but in XIV it only can access it via cross-classing from CNJ. This is no different than a RDM only having access to Fire/Thunder/Blizzard/Aero/Stone/Cure from cross-classing.
The swords are also not just for appearances. They have stats on them that benefit the magical side of the mage. In FFIII the 2 best weapons a RDM could equip gave +15 and +5 to all stats (Ultima Blade and Excalibur respectively). FFXI their mythic weapon has the highest magic accuracy that they can achieve. In FFTA/FFTA2 they could only equip swords and their swords had magic power on them. FFXII:IZJS even went way out there and made them very proficient in great swords so they could use Ragnarok, Ultima Blade and Save The Queen.
Their armor has also been light/leather armor which is contrary to your idea of a mage. RDM-only armor historically has been light/leather armor. Like the Red Jacket in FFIII and artifact/relic/empyrean armors in FFXI. They could equip cloth gear as well but their iconic, RDM-only armor was not cloth.
In my version they'd obviously have physical stats on the weapons and armor (as stated they'd wear BRD gear) but Arcane Stance (named it that due to instances in the franchise where only the RDM can use Arcane Magic) allows them to swap them for magical stats. They'd then function pretty much like you are wishing them to, only they'd be getting the "iconic" magic from cross-classing (exactly like a PLD does now in XIV). Instead of getting powerful casts like BLM or WHM they're getting weaker casts but much faster (30% base before gear and not counting abilities like Dualcast).
In FFI RDM had equal STR and INT. In the original FFIII it had equal STR/MND/INT. In FFV they had equal stats in both strength and magic. FFXII gave them equal parts magic lore and battle lore. FFTA and FFTA2 gave them equal magic and attack.
So essentially RDM has never been an iconic "mage" by your definition. It's primarily been an equal parts caster as melee. I believe you are thinking of Sage which is the magical variant of the RDM in FFIII. In my version, thanks to Arcane Stance, they follow the history of RDM being equal parts caster and melee.
But in any case, thanks for the compliments all![]()
