This is a good idea, you'll have to really work to do it, but there are issues with this. A group of people could do this, get the set stations, and open their doors to everyone to do it, and by offering the chance to make the set, it would mess with the economy for set's. (Is that the right term to use?)
Maybe if players who want to use them also need the achivements, or have atleast beat said dungeon on veteran, maybe?
