Thank you for your replies. Unfortunately, it raises the same confusion I'm seeing in game. A lot of players also don't seem to know how they received their titles, so it's hard for me to tell if something like "The Heartless" is a Dark title or not.
The thing that bothers me the most is "Ruthless" appearing above my head at Dark II. It looked like I was receiving a title, but then I didn't see one. Hopefully a friend or two will hit Dark I and II tomorrow and that will tell me if I'm glitched or not.
I wouldn't really mind the change too much, I just want to know if a change occurred.
