Watcher Dev acknowledges widespread Que issues and is hopeful for 6.1 fix due too redesigning the way ques pop!
Initially in reference too Ashran but then expanded to cover Ques as a whole.
For example I was queued on my priest for over 15min when game ended. They all queued got right back in - including same healers. I didn't get a pop. So no real logical explanation for that.
