After all this years, maybe the simple concept of dungeon has become obsolete, that being said wildstar had an interesting idea : While you do a dungeon you'll be given mutltiple critical choices that result in different encounter and different area to go through (most of the time 3 choices).
The choices were done through votes of the party members. (could be randomized in FF14 if the votes are equal)
But yeah overall dungeon concept is in dire need of renewal.
