Matchmaking,,,, is there an easier way?

Playing on Xbox I’m finding it impossible to get on a Mayhem 3 Circle of Slaughter. (Maybe I’m doing something wrong)
I’m set for Mayhem 3 and usually get a group on no Mayhem or 1.
Or I always get the Cistern when I would like to do the others.
End game is wearing thin and this problem is making it worse.
I have beat the game 5 times and just want to kill waves of baddies now for good loot.

Do it solo then?

yeah but… :frowning:

I have the same problem, only loads cistern, and when I go to proving grounds locations, it doesn’t even let me collect the new proving grounds EVEN THOUGH IVE BEATEN THE GAME.
