I agree it is kinda pointless to open KM to everyone, if you are going to keep the map for 21+ (or whatever the level is).

On the other hand, I disagree with the notion that mobs there should scale to the level of the players. I don't think a huge crash of lock prices will be a good thing for the game as a whole.

p.s. Of course no-one farms useless jewels in crypts.
