Diffuse is right. Umbra is nothing compared to the embarrassment that was the entire last map. There were only a handful of towns that weren't big buildings, some were prettier than others but they were just a single large building.
However, I think they deserve to be pressured so that others do not do the same as they have.
As for what
MajorasMask was saying, every town needs impenetrable parts somewhere, or else it's a pretty shitty town. If the only thing between raiders and you is the doors and walls of your very home, you will get exploited on, or just pulsed to death by casters. Unless you live in a tall home, but still claustrophobic compared to the upper city/under city model.
