I was thinking that maybe architects or some other skill type should be able to craft crafting stations for the various craft skils.
Cities will have the option to be open to everyone, even non tribal members- so why not have an option to put down real crafting stations for each craft type. (woodcrafting station, leathercrafting station, etc.)
The benefit to using a crafting station would give you a slightly better roll on stats. You would still only be able to craft whatever recipes you know, the only difference is that when you make the item using the crafting station it will be slightly better in stats than without the crafting station.
If the tribe allows it our cities will be open to everyone, this is just another thing to help encourage people to visit more of the cities in the game other than just to pick up player made quests and trade.
It could be like a vending machine- insert coin here- and the coins go to the tribe bank- or the crafting station could be empiteid of ti's coins by the tribe leader. Also, the tribe could set the cost of using the crafting station. Raiders could break the machines to steal the coins.
