More enterable buildings, please!

[Iscah]

Basically I'm pointing at things like the House Fortemps in Ishgard, the Ocular in the Crystarium, where there is just "a guy" outside that you have to talk to that acts as a story roadcone to entering the location. Why is this guy there. Why are they OUTSIDE. These places are not a royal palace with a guard booth. It's just a noble's house, or the equivalent of the mayor's office. Why do the doors not automatically open? Why are the NPC's not just standing inside?

This is pretty clear – it's because they haven't built the whole manor, just the one room that you load into, and because they don't expect you to trudge up and down Syrcus Tower every time the Exarch calls a meeting. (That and they probably don't want to have to resolve exactly where in the tower the Ocular is located, but anyway.)

If the developers cared enough to allow people to explore, they would probably go back to the ARR maps and make sure there isn't a single "no entry" door. Either it opens, or it stops being a door.

I disagree. I think it's unrealistic to expect to be let into every single locked door, and having them there makes the city implied to be much bigger than the devs can afford to model it.

Towns (and the setting in general) already have a problem with looking extremely low-populated with only a few buildings each. Removing doors that don't go places would be detrimental.
