Definitely am open for a more complicated extraction process from pickables, too. I like to get some corn oil.
Butchery is dumbed down, but I wish they could make it so that you could butcher both as 'autodrop' certain things as well as 'focus' certain mats. Again, more of a chance for depth. Even like choosing how to butcher something (various diff ways,) and giving different results.
Butchery is one of the main money gens in this game. Money from NPCs, a lot of the time, at the very base. Where as metal and other things are another sort of value as they do not generate vendor money, but are player materials. So, in a lot of ways butchery is just whee but we need to simulate it with stacks so you need to cart it back.
