Yup. We need to be wise with each settlement but also try to be realistic. People want an equal amount of regions everywhere. Historically and realistically this is not how the map should be made. Anarchon has a good theory. The center part of the map should have the most cities, as you extend outwards there should be less cities.
So Germania, Britannia, the Steppes, India, Arabia, and the Sahara should not have a whole lot of cities.
