So, i'm was up late last night and had more caffeine in me than i care to admit. But, in my caffeine filled haze i thought, wouldn't a new method of trading be nice, though at a higher level... So, I said, what if you could now upgrade from donkey to caravan and then to... merchant ship. You wouldn't own the ship, you would just rent it at a new trader's only port and you could trade bigger contracts without the whole shardstar process. You could add in a few different ports and maybe some not so known "trader only" ports that don't really have much more than a traders outpost and a blockade that prevent advancing further into these "unknown" lands. I don't know, but this seems like a good idea for higher up trading and it would open up visiting the islands again cause I'm not really sure if anyone does it these days.
