Differentiate me from other players with same class!

[Rykken]

So I have been playing the game for a week now and just hit level 30. It is a fantastic game! However, I was wondering what really differentiates my White Mage from other White Mages? Or any other class for that matter.

Other than attribute points, armor options and player habits, is there any other system in place to make me different from others of the same class? I ask this because there are quite a few games out there have some other system in place to personalize your character, in addition to the above mentioned. I do know that when systems like this are present, class imbalances may arise, but I was just wondering. Maybe I missed something.

Thanks!
