In my current England game my mission is to gain control of our trade, aka build a COT on the isles. however, if I understand correctly, the COT the province currently trade through has to be worth over 800. Antwerp is around 470 right now and it seems to be dropping rather than rising. How am I gonna do this without sitting back for decades hoping the value rises, or conquering a bunch of COTs and destroying them? That would kind of be a pain in the ass to do. Should I build marketplaces everywhere or won't that have any effect?
