EU: Role only had one ship class trieme and not much to do other than fight, blockade and transport troops. Will this be different in Imperator?
Protect trade routes. Without the Mediterranean trade, no classical cultures. Without a decent fleet to protect the routes, thousands of pirates.I am not against making naval side of warfare more interesting, but what more could the navy do, aside from what you have already mentioned?
Not the second half of option b in any case. Most of the time they tried to beach the pirate ships (by surrounding them with their large standing fleets) and then defeat them on land.There were only two ways to prevent rampant piracy and sea marauding in the Mediterranean
a) Keep an active, standing fleet with decent number of ships capable of fighting, patrolling the routes.
b) Take over every inch of land around the sea and surround it completely. If the pirates can't even find a place to land, what else could they do other than surrender or starve?
....Guess which option Romans took.
