I use to play a lot of 2v2 and 3v3 with random people vs A.I. on hard or very hard slowly working my way towards the Supreme Command achievement.
But with Heart of the Swarm they changed it so that when you choose to play vs AI from the Matchmaking menu it sets the difficulty depending on how you preform vs A.I.
I do not want to play every other game vs Elite AI and some times I just want to relax a bit and only play vs Harder A.I. but I still don't care about what map I play on or with who as long as it counts towards my achievement.
Is there a way of looking for vs A.I. games as it was before HotS where I can set my race and the difficulty and play 2v2 or 3v3 with random people on a random map?
