The trading lifeskill is pretty dead and is only used by people maybe once a month after hitting a certain level. I think making the trading system more like the Bartering lifeskill, but on land using wagons and could have a few different nuances to make it a more active lifeskill. The infrastrucutre, wagons, etc are already in the game and you could make the trading buff something you focus on getting before starting your trading sessions and the better the wagon, the more trades you can do with the buff before it runs out.

Thank you for the suggestion, I will send this off to the devs today!!  :)
