While I dont mind the dungeons, I cant help but feel that after I've completed them once, they're a total bore.
The mechanics, the areas, and the bosses are all neat, but only while they remain fresh and new and you're trying to learn them. So I was wondering, why not... have something similar to randomly generated dungeons for players to go through?

The idea I had in mind was something along the lines of :
Go to any dungeon zone. (You know, the doors that just open duty finder?) And say, you sacrifice an item to determine the parameters the dungeon is based around.
Depending on the place you sacrificed the item would determine the aesthetic theme of the dungeon; but also the types of mobs and bosses that would appear. The level, or value of the item would determine the strength of the mobs, as well as the value of the drops.
