Anyhow, alchemy is a good idea!
Xet it would help to set skill max., allowing each player to either focus on 1-2 high skills or be able to reach medium levels in all skills ... so the "high level" artifacts would be limited to crafters that focus on specific skills - trade within a tribe and across regions would become a the natural side effect (for specific "high end" goods), probably also true for "high end" products that are needed in other skills (like "leather-type-stuff-thingies" for tool/weapon/wraincrafting) ...
AFAIK: Jordy has planned for that (skill max) to come - so we will see how it all works out...
BTW: anyone wants to trade 10k bricks
