What is the point of having any Uniques at all if they won't drop anymore? Also what is the point of updating them? Why not just remove them all from the game except the boss ones? Makes much more sense IMO. If they update them, people could play the game until its end and only ever use Uniques. New players would probably always be asking what that brown item is when inspecting someone.
I just see no point to having them in the game anymore, other than it being a courtesy to the people who spent time making them perfect..
