To be fair, even when they gave us choices the community ended up settling for the 'right way' to do things. Toto-Rak comes to mind as a dungeon with a couple paths and places to explore, but if you so much as go the 'wrong way' in there it can lead to a fight. If they're going to allow us more freedom with dungeons they're going to have to ensure that the choices are all of equal merit - but even then people will doubtless decide that one route is better.
