Dual Wield

[Nahara]

I don't think it'd be that hard to give the gladiator's second job the ability to equip two swords instead of a sword and shield.

I highly doubt this, simply because of the amount of stats on the swords. A main-weapon and shield combo is supposed to be roughly equal in stats to a two-handed weapon, with the main weapon supplying most of your stats while the shield supplies the rest of it. To put some fake numbers to it, think of the main weapon as holding 70% of your stats while the shield holds the remaining 30%. If you were suddenly able to equip two main weapons, you've now got more stats working in your favor than any other class or job.

The only way I could see dual-wielding working stat-wise is if it was like the PGL: you only equip one weapon, which has the all of the appropriate amount of stats on it, but you're shown as wielding one in each hand.

That is exactly the point and thought I was wanting to get across

I agree with what some others have posted.
With the current classes, I don't see dual wielding swords happening since class and weapon are linked in this game as it would require a new class.
Dual wield via paired daggers/short swords would most likely be implemented with a Thief class which could potentially evolve into Ninja and Dancer as jobs.
As far as parrying daggers as off-hand items that potentially increase parry instead of block, I could see that being implemented with a Fencer class that could evolve into Red Mage and Runic/Mystic Knight Jobs.
