Dual Wield

[Sylari]

For a new class yes, for an existing class wouldn't make too much sense to me

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. Would make more thematic sense than a DPS with a shield or somesuch.

That said I think the most likely candidate for dual wielding would be a thief and ninja class/job somewhere down the line rather than modifying an existing class.
