Didn't see a suggestion thread here like in housing, so might as well make one.
I was thinking that SE could add a random aspect to the dungeons to make them less routine to those of us who are used to some of them.
Like say a rare optional boss could appear and offer more exp and better (or unique!) gear then the dungeon it appears in. Could also extra tomes in some dungeons.
Or a secret room could appear with lots of chest in them for mats or gears.
