Due to the newest patches, which will decrease your trade efficiency by one for every trade agreement, the trade has become useless. Let´s say I play Sweden and I send merchants to Mecklemburg and Courland. I pay 2-5 for each placing and I gain 6d in a year(or is it month) for them. Anyway I get competed away very often. So it means I gain 1d a month. So what is the use?
