What class is Thancred? (Spoilers)

[Lienn]

Weapons are specific to class in XIV. Unless Thancred is somehow special (which I admit is not impossible) he is a gladiator since he is using a dagger. That's my take on it.

That's not 100% true. weapons are what define classes here, but there isn't only one class for one kind of weapon. You can see CON and THM using the very same weapon type, being only different models. The same would happen to GLA...GLA has its own swords, but still we can have a blue mage having its own sabers, thiefs and jugglers having their own knives, red mages and fencers having their own rapiers, etc. They all would be at sword group, but not at "Gladiator's Arm" group.
