Now it seems to me that some cities are impossible to manage. I play the Junii campaign and have conquered and held 2 major Gaul cities for about 50 years now. Every turn theyre on the brink of rebellion. No matter what i build or do theyre never satisified. The only conclusion i've found is since the cities are placed on the frontline they are under constant siege and trade routes get robbed.

Is there a solution for rebellious cities that doesnt include mayhem and murder?

or do i have to

1. Give the cities back and the reconquer it and massacre the towns?
2. Conquer all the enemy cities nearby? Which just leads me to another problem. Those cities will get rebellious.

It seems like an expansive doctrine is the only one working in RTW, a slower balanced warfare with it's fundaments in trade and diplomacy doesn't seem to work at all.

Give me some hints.
