If the trade routes indeed feel overpowered, I'd suggest needing the Carthage city state while you're at it. With the heavier need of encampments in this mod, whoever is sovereign over Carthage has a game changing number of caravans to construct. Another possible issue to consider is rebalancing civic techs to fall more in line with the slower science techs. I'm finding myself accidently 2 eras ahead of myself in civics compared to science. Makes warfare awkward as my pikemen besiege cities defended by cannons as steel ships pull out of port to harvest crabs.
