Please make them favor items you don't have in your collection. I've spent the last 3 days getting the schematics, which is a grind in and of itself, only to be punched in the face with an item I already have. Look, this would be fine if you were able to get multiple schematics each day, but you can't. So please consider a less time consuming solution, because my sanity can't take another defeat, I just want that wayfarer badge and move on.
