I've been hoping for randomized dungeons for a long time now, but not really getting my hopes up that much because of the evolution of dungeons currently. People have complained about 1.0 dungeons apparently? They looked like they had more stuff to do than ARR dungeons though so that might be the case. People also have bad experiences with their party of Duty Finder because of different goals. Some want a full clear while another wants to skip things to clear faster, or even speed-run. I believe that's why Heavensward dungeons are so linear and have gates that require you to kill trash mobs in order to progress.

Randomized Dungeons is something great this game can have, but it's better off not being available for Duty Finder.
