new matchmaking is on production now, so you can just log in and play, it was not possible to test it properly on OTW, thats why there few problems but not as bad as crybabies complain.
We were playing group of 3 golds and wait time is usually around 10-15 minutes, had 5 missions in 2 hours, Group of 2 had very short waiting time, around 1-2 minutes.
For sad jokers, maybe if you would give sime thought to how mm works, you would realize that you will get any match after certain waiting time, but removing your ready state will remove you from que and most likely reset your timer, that will result in restart of whole match searching for you.
