What I would want to see is a dungeon out in the open world that get more challenging the further you go in them and its without any waypoints in them.
Ofcourse the rewards at the furthest lvl in the dungeon should be better than at the first few lvls/floors of the dungeon. Maybe a huge hole in the ground or a tall tower. That way you can work together with the people in the open world to try and get as far into the dungeon as possible all the while trying to keep everyone alive.
It’d be awesome
