With the arrival of Guild Houses, and the continued existence of important buildings that always occupy the same disposition within Hydlaa through the updates, I believe it's justifiable to add a bit more depth to the organization of the towns. I'm not sure if this exists already, and if it does, do forgive the redundancy, but I believe making up Street names and such is becoming necessary.
Having an actual address helps a lot, since some people might prefer to tell someone to head to Jeffer's street rather than pointing or being followed towards it.
It's obvious that it would also add to the role play experience.
