Oof, sorry about this, folks. We’re working on it as fast as we can.
In the mean time, just so you know: I’ve noticed a lot of people commenting that they’re restarting their search after a few minutes. You definitely don’t want to do that—the way MM works, it gets more forgiving the longer it runs (until it times out), so if you restart it every few minutes you’re shooting yourself in the foot.
Next revision is now live, attempting to better balance the MM rules so that we’re still trying to balance the teams as best we can, but we don’t want top-tier players left out in the cold. Give it a whirl, feedback welcome.
