Gladiator flavor text implies that some gladiators forgo a shield in order to 'strengthen their sword arm.' Yet, there's absolutely no reason to do such a thing, unless they intended to add another GLD-based job at some point that didn't use a shield. Perhaps a 2H sword option? Maybe dual-swords?

SE also needs to stop being lazy; the Rogue/Ninja 'dual weapons as single weapon in main-hand slot' thing is absolutely stupid and needs to be redesigned. Even if that means not keeping their promise for a 2.4 release of the class/job.
