Bretonia Rheinland trade is a bit crap, sorry, our best route is about 24,693,876 per hour in a 5000 (refugees>military vehicles). The Best Kusari rheinland route is some 29,022,658 per hour, and there are barely any pirates there to pester them.
Unfortunately thats where LWB must pirate, where Hessians must pirate, if a Rheinlander wants good profit and less risk, they can simply go to Kusari where most of the routes are far better, the only ones to hit those traders are Bundies.
I get better profit with a smuggler route with zero risk and 4300 cargo, not just a bit more profit, a crapload more, several milion more per hour.
All the while my transport doesnt get Cd'd constantly by npc's, pirated by 8 corsairs, or has to pay attention and do that laboursome task of clicking on the trade lane and pressing dock, only to have it interupted a few lanes down, and the profit is hurt by interuptions.
Wonder why kusari has nothing but traders? yeah, it's awesome trade, thats why, bretonia's best trade goes to Kusari and all those zoner routes from gran canaria head north too, shame we're at war huh? you can make 31mil an hour BMM bases > Samura bases, oh, if only we had a neutral party with 5000 cargo to do this run?
Current trade system has killed it frankly, it's based on Zoner trade hubs, blockade runners, Smuggling, piracy (but no traders outside zoners, smugglers and blockade runners to pirate?) and Kusari.
