Honest question: If every player/class/job is equal,who is unique? (Gameplay topic)

[Canadane]

Complaining? I'm pointing out facts about them, big diff. If I was going to complain, I'd make a post about how unoriginal the gameplay is,how the current state of the game reminds me a lot of WoW, and how tedious it is to farm solidery tomes.

Oh wait, I just did. See the diff?

Perhaps "complain" wasn't the right choice of words.
How would you give each class it's fair assessment if you haven't played them all?
