I'm glad that after this patch there was a hotfix that fixed a major issue where the dungeon finder would never teleport you to the dungeon, making random dungeons impossible, however the dungeon finder is still extremely bugged and impossible to use in certain situations.
We have an existing group of 4 people in a group at the moment. We want to do a random daily dungeon. Group leader queued us for a dungeon, the dungeon finder did a ready check, said the group formed successfully and then... nothing. We were not teleported anywhere. The dungeon finder went back to saying we were queued.
So, we disbanded the group, got back together, and tried to queue for a random daily again. This time it did a ready check, said the group formed successfully, teleported us to Fungal Grotto II... and then said 'removing from area' because somehow it thought we were in the wrong instance of the dungeon.
So we disbanded and re-created the group for a third time. Now we are waiting for 15 minutes to re-queue so that we can probably have exactly the same issue again. We just want to do a random daily dungeon.... Are we going to see a fix for this..?
