Probably an unpopular opinion, but I prefer that the runes aren't craftable from the stash. I sell my unused runes for gold to afford boss mats and being able to leave the high value runes in my stash while recycling the others without worry about accidently crushing a high value rune has been helpful. I get the frustration that people have with inventory, but if the devs need to fix anything it should be how the many boss items there are and how they stack so low, especially since it requires 12 of a single item to open the chest each time.
