I hope this game doesn't follow WoW's expansion routine.

That's because the classes in a game like WoW HAVE to be customizeable. You can't change your class in WoW. Once you pick it, you're stuck in it forever unless you make a new character, so they give you different ways to play your class so it doesn't get boring. In XI and XIV, you don't have that same limitation, since you can freely switch your class.

In WoW, you change the fighting style, but you can't change the class. In XI/XIV, you can't change the fighting style, but you can change the class.

You cannot change jobs where it matters.
Those who level alts gets an extra 300 myth per week and 5 coil turns. Due to alts bypassing restrictions. Armory system is flawed and penalizes secondary classes.
