Hey folks, just started playing about a week ago, having a great time. So many thing remind me of past FF games which hold a special place for me.

Anyways, I'm leveling a Gladiator, currently level27. Really like the class. My question is do I have to level other classes to be an effective tank? Or going pure Paladin good enough? I've always been a min/max type of guy so if I need to I definitely will. If so, when is a good time to level the other class? Wait till max or just start now and keep them all balanced?
