With all the variety of crafting items and need for basic reagents to make more complex ones, why not add a Deconstruct/Untransmute option to crafting so the extra complex reagents can be broken down back into basic and then allow for retransumation for different complex reagents? In the end the same amount of reagents will be used, but in this case just more efficiently. I have tons of complex reagents sitting around not being used that could be put to better use if I could break them down into basic reagents again.
