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

Having not played all Jobs to their fullest (You only have four (SCH/PLD/SMN/MNK) of the nine jobs capped,) I really don't think you are one to say how they are different or not. A level 30 job/class plays quite a bit different than a level 50 one. Gear changes play style as well as overall abilities gained. You should perhaps cap the other jobs, and explore more how they are different in mechanics and play style before making anymore decisions there-in.

@OP: It depends of the amount of details and precision you want.
I can ask you what sets apart a cat from a dog and debate with you by saying that they are both fluffy animals with 4 paws and a tail, therefore they are the same.
If, for you, a ranged DPS is ultimately the same thing as a melee DPS, I can say that typing on a forum is the same thing as playing a video game on PC since you press buttons on your keyboard to do both.
