Damn good storytelling. This is SE and that is their forte.
Youre putting unrealistically much weight for storytelling when everything else reminds us of the earlier reincarnations of the classes. I think it's on a kinda shaky ground right now, buuut that may bee just mee.

By the way, none of my examples went against what our mindset of FF classes is. So I'm not sure where thats coming from.
What goes against our mindset is when you level both dark knight and paladin at once. You're a good guy and a bad guy.. at once! The 'damn good storytelling' says something else but the armor, the skills and the playstyle tells us a different story we're more likely to believe.
