I think you can truly feel the current state of the game from the current war. There is a big shortage of people to fill the regions. So many regions are left unattended.
Yup. Though it's also partly due to nobles being concentrated in the wrong places. Sirion has lots of nobles but it still has plenty of rogue regions because its leadership is rotten.
Meanwhile realms like Perdan would probably be fine if they just had a few more nobles.
