I was considering White Mage, but remembered the Dawnsword was a thing and wanted to try a spec using that. I would have gone White Mage if the Dawnsword was a Catalyst. But even without it, combined with the Wing's of Asira made it an Awesome combination. Being a Dual Wielder and immunity to Disarm helps a Ton to make sure your defense's are up.
To me, it'll always be wild that the pure Dawnsword isn't a catalyst. It's meant to be used by a holy warrior, a paladin of outstanding virtue. And making it a catalyst wouldn't even make it super OP or anything, considering how far into the present game you have to get, in order to even unlock the mission to get it. As it stands, there's precious little equipment that appeals to a paladin-isk build, at least if you also want that paladin build to be proficient in using white magic by way of a catalyst in assisting them. It's wild to me that the SG is more appealing stat-wise to a build like that, than a magic holy blade meant for a strong paladin is.
Don't even get me started on the fact that it's a light weapon, and as such appeals more to dual-wielding fighters than it does to the type of character that it feels like it was actually intended to appeal to roleplaying wise, whereas the corrupted Dawnsword I could totally see being used by a casual dark warrior type character who wants to dual-wield it. Personally I'd rather see it lose the light status in exchange for the catalyst status. That would make it an ideal sword and shield paladin setup, and would suit it far more thematically.
