Samurai

[Shippuu]

At least samurai aren't running around casting magic spells at things.

Funny you say that, because in Final Fantasy Tactics samurai did pretty much exactly that. They cast spells from their katanas creating all manner of offensive and supportive abilities. These things were also boosted by their magick attack and not their physical attack stat.

I have no delusion that FF Samurai are even close to the historical fact ( this is true of every single job in a fantasy game), but at least there is a historical knowledge to pull from. *Samurai once existed, the knight who pulled dark power out of his soul to shape it and use it against his enemy did not.

Knight's existed and of course they had no dark magics. But Samurai in this game would be no different. It's a rough basis and that's it, whatever lore and abilities they give them will add flavor that is fantasy. In Tactics they summoned spirits from swords, in FFXI they were demon hunters, etc etc. It's no different then our current Paladin, which is just called Knight in the Japanese version. Their "Knights" wield holy esque magic abilities.
