I tend to think of things in terms of time value since its my scarcest resource. Looking at the transmute system -- which I like -- I ran a calculation of the time cost in terms of gold if i were to focus on either (i) harvesting or (ii) getting crystals. Obviously there are side benefits to both, and variables can range, but here are mine...roughly...
This is for a well coordinate potion component farm (single component)...I imagine ore could be more valuable.
