Basically Blizzard is selling all your residuum for you at the end of 8.2.5 and will give you silver in exchange.
I think this is the wrong approach because it disincentives farming mythic plus and begs the player to stop once they have acquired all the pieces they want. It is true that they may have acquired all that.
Personally I would prefer getting Alt Residuum Coins instead. I would enjoy the fruits of my labor more instead of getting scraps of silver for hours of preparation. I likely spent more on flasks alone for all those mythic plus runs that this silver exchange will give me in full; it is not a good exchange at all.
What do you all think?
