We would definitely need a limit on how many such titles to show. Possibly only allow it from guilds with at least a certain number of members, too, and only elder ranks. I don't really like the idea of just any lord creating his one-man guild to give himself the title of Emperor of the Universe. Nor every single noble having extra titles, it already feels like there's too many titles for everybody as it is.
Not sure how I feel about custom public titles being granted by guilds, either. Always felt that realms should have some powers about that.
