Hope when we do rework some economic aspects of BM, we should have some imbalances. Like realms with mountainous regions producing high amount of metals while producing little food or something like that. Trade was necessary for men because people didn't have everything they needed.
Yes, something like that is still under consideration. However, under the old system that would have been an insane amount of crazy and bug-prone code.
Right now, there is nothing specific on the table, but my thoughts go in two directions:
a) something like in the Civ games, where if you control a resource, you can use it, and you need a certain number of resources for some things. So controlling that mountain region may give you x points of metal and some high-end recruitment centers need metal points to produce soldiers.
b) maybe with the new trade system, these resources could be tradeable goods. I'm really not sure about that, though.
