Yes, i can confirm. We tried to get a group, but kept getting " someone declined..." after succesful ready check. 30-40 mins in a row - and we were tank and healer.
Also it got worse after today's patch. Yesterday we had same issue but finnaly could do it.
That sucks and super weird a tank and healer you guys waited that long. Usually when my friends are on (both tank and healer) we wait no longer then a few minutes. Trick we do is make tank crown and queue. Almost instant!
