Free version of Dalewj's second book (Diaries of Afterworld) is now available!
The idea to make it more convenient to craft anywhere isn't a bad one, but it doesn't seem to fit the devs vision. They have already stated that crafting will be broken up further when more cities become available, so you wouldn't be able to craft a dagger pugio and axe ru medium in the same place for example. As time goes on and Aw develops, I'm sure the devs will revisit the issue so they can empty wallets faster. Another possibility, since we can see any storage from anywhere, would be to be able to remotely craft if we have all ingredients in that cities storage, then travel to pick it up later. This also leads to another possible use for couriers, Give a courier a sealed box that they can place into your storage in a city, then you could use the materials to continue crafting without leaving the area you want to skill in.
