I 'd rather not think of the Armory as "incomplete", so much as a cog within a much bigger machine (in this case, the machine being character development).

A few other tidbits I'd like to comment on...

Dual-Wield: Making it is universally obtainable skill had a tendency to be a bad idea, and to be quite honest, the "Twin Sword" method (a med ATK 2H Weapon that strikes twice) tends to lend itself much better in the long-term lifespan of an MMORPG. While players do enjoy the freedom of using 2 unrelated weapons, the effects are less than optimal on the game's actual play... So yeah... I'm more of a fan of systems which only have 1-H Weapon and Shield/No Shield or 2-H Weapon, for good reason though.

As far as Samurai-type jobs go, the Parivir might be kind of interesting (a more accurate, glassy marauder), but this would involve using the same weapons as the Gladiator (assuming katanas would count as swords), so it would require an actual job, as opposed to a weapon class. Heck, Red Lotus is already a great place to start for this.
