Why did Did no one recognize Sazh or Vanille when they were basically the monsters? 

It's been awhile, but their world seemed to miss depth in comparisons to the other worlds of the FF13 series which is usually slowly explained through townspeople.

Especially now there is apparently God which is never mentioned :T

To me it looks skimpy for a Black Mage. It could be worse but I still disapprove of it :T
