Jobs start @50?

[Petori]

While I can't offer too many new details, another thing I wanted to clarify about the upcoming job system; jobs won't be unlocked at rank 50, but when leveling a class up and it hits a certain rank you'll be able to unlock the related job.

Thanks for more information. Will class get EXP while playing it's job? For example if R30 GLA unlocks PLD and then you gain a level as PLD, will GLA be level 31?
