To add another specific example to this, why the heck does a noble not have any dialogue options in interactions with the vampire dude? Or scholar with the wizard, starting from that shared experience, you know?
Yeah, my first character was a noble, and when Astarion told me, "Oh, you're from Baldur's Gate too? We must move in...different circles." I felt legitimately offended and wanted some Noble dialogue tag to shut him up.
