What I would like to see is for more maritime routes. Realistically speaking, sea travel was one of the fastest ways to get anywhere in antiquity. A ship could sail night and day, and do so at a speed that horses would be hard pressed to match. It should take proportionally less time to get somewhere by sea than by land. This is reflected adequately I think when you compare the difference between traveling from Eidulb to Golden Farrow by sea as opposed to by land. I just wish there more such routes. Realistically speaking, any port city should be reachable from any other port city by sea. In game terms, I wouldn't expect the routes to be direct, but you ought to be able to eventually reach any city on the coast from any other city on the coast traveling exclusively by sea from port to port.
