PC/NA. Queued as tank and it pops instantly but very often someone is not ready or whatever and after 45 seconds it should requeue me. It does but it doesn't pop anymore. I can wait in queue indefinitely as tank and in corner it says I'm queued. When I leave the queue and try again i instantly get ready check again. Sometimes it also boots me out of queue if someone "declined".
Healer and Tank queued for random normal. 45+ minute wait, we finally gave up and went to bed. We also dropped queue and then requeued a few times, to see if it was doing the "stuck" thing, so it was probably closer to an hour or more in queue.
Last night, a healer friend (mid 30s) and I, on a tank (a max CP character), tried queueing for a dungeon. We spent about 15 minutes waiting, tried requeueing a few times, nothing worked.
After I swapped to a level 22 (also with tank gear, and as tank role), we received instant queues for the rest of the night.
Trying that again tonight, this time with a friend that is above 50 but below max CP, so I'll report in.
