I am not sure if that has been answered, but so far I know that the Slot 1-5 Uniques will become legacy and won't have much use. Furthermore, the recipes that interact with Uniques will be going away as well. So how will this affect rings and medals? Will the reroll Unique medallion recipe go away? Will the Exchange 4->1 Ring for Limbo Box Rings go away? How about the reroll stats recipe that can be used for Unique rings?
If this has been answered already, can someone link the post?
