I understand your frustration, and it's something that Plainsfolk and Sunseekers and Hellsguard have to deal with, since their names are supposed to be full Forename and Surname all the time, but game mechanics doesn't let you do that. It'd seem like city names would push you to create a 2 word name, but you run into that problem where you'd be "Blade Glory" or "Lieutenant Tia" most of the time, with no option to do as Fran and just be "Captain First-name"

Until we get an option to go by our full names or just first or last in all cutscenes (which sounds like a huge undertaking), there'll be some disconnect between naming conventions and game.
