Fiefs are imbalanced in a aggravated way that affects everything else, it seems Battania holds towns with whooping 4 villages each, which explains why they steam-roll so often, whilst, say, Sturgia only holds 2 towns with 3 villages, and the rest is scarce with 2 each. That being said, the most OP nations at the start would be Aserai and Vlandia by the amount of towns, but I didn't check the amount of bound villages to them... In the end, that breaks the economy by making certain towns extremely wealthy whilst hindering other towns with 2 villages, making those depend upon you never conquering nearby towns and keeping all nearby castles (this way you boost the number of villages sending peasants to your town, making it richer). If you decided to conquer the nearby town, you'll break your main town economy. So, what's the best strategy right now? Conquer Battania, from there you'll be able to steamroll the early "kingdom" and soon enough you'll be snowballing everything.
On the other hand, if you start by any of the Empire's territories, you'll be playing roulette, to be at least somewhat efficient you'd need to take the cluster of towns located Northwest of the Kingdoms, notably you'd need to wage war against both Western + Northern and steal their 3 village towns, you'd still be in a disadvantage to Battania.
I think the World map needs balancing, proper balancing. Towns should have a medium equivalent of bound villages, else you're condemning certain AI factions / Lords to always be struggling.
