I imagine some basic things will be obvious enough. I mean, a character who heals using magic is a white mage, and everyone knows that.

I'm currently not a fan of the new naming conventions they have. I mean, gladiator? Pugilist? Are we playing Final Fantasy or Age of Empires? Should've stuck with the original styling of names, I reckon. But that's just names, and so long as the gameplay is good I'm sure I won't be that bothered.
