Naginata may be complicated since I believe that most of the weapon designs that would fit it are already Lancer/Dragoon weapons, While I suppose they could pull the same trick they did with Ninja and Paladin, but that would be a rather large amount of weapons Dragoon loses that they need to replace. (Of course, it is ultimately the same number of weapons they'd need to make, it's just that I feel if you say, limited Spears to pointed thrusting weapons and Naginatas to single edged cutting weapons, you'd be doing both sets a disservice.) But it's just a weapon choice, no reason to throw the baby out with the bathwater. Haven't played XI, so I can't say I can comment on Iroha beyond her walking up to crabs and giving them a stab (her basic gameplay in XIV)
And unfortunately for both sides of the discussion, Severian is hardly arguing against a monolith. I'm certain there are some that want a dual blade wielding mage knight simply for the aesthetic. Though I do believe most of the people asking are aware of the necessity of XIV's system for it to require a new type of weapon. He did address the issue with imbuing as a separate step when he quoted me, Though the summoner style "the imbument is also an attack" would address that as well. Of course, as noted, Summoner has already dipped it's toes into this one, so a bit more would be needed to differentiate it (Though I feel that the style wouldn't be facing as much backlash on a melee build as Summoner is right now.)
