An idea to keep crafters awake and actually feel that what they are doing is worth while, my suggestion is that when gathering the raw materials there is a small chance of digging up a form, yes i know it wouldnt make muchs ence atall for trees, wisps and the fabric area but eh bare with me.
The chance of getting one would not have to be big, infact it could be tiny but justthe fact that there is a chance would inspire atleast some to carry on digging!
The form/tech you get could be based on the material/tier resource you are gathering.
sure in some of the areas it doesnt make alot of sence, but does everything in this game? no.
