Some of the new crafting recipes for legendary or set items require regular white items in order to craft them.
I've been saving superior or masterwork white items for eventual use in these crafts. But it occurs to me that I have no idea if these are even worth keeping for this use. On one hand, they're pretty rare to find, and that limits how many I can craft. On the other, if they actually do provide better quality crafts, there's an advantage in using them. But if they don't, I've been passing by lots of white items for no reason at all.
Does this level of quality for white items play any part at all in these crafts?
