Been like this a few days for me as well. Average time says 2-3 minutes, 4 HOURS later, nothing. Other toons, 2 or 3 minutes and in. My tank is instant obviously but my other DPS get in relatively quick. Its just my Drakthyr that has super long ques and never an invite. I am starting to think its deliberate on Blizz’s side so its not 4 Drackthyr and 1 tank. In their weird logic, they prob think that will look bad.
