I mainly try and play the matchmaking systems of 1v1 2v2 and 4v4, since most of the custom games are either locked to super high ratings, or are on terrible maps.
But they queue system is janky and confusing. It takes forever to get a match sometimes, and often the queue will say there's 10 people in there, but when the timer hits zero it'll still say 10 people in the queue and it'll do that 10 times without getting you a match.
I'd much rather actually play a horrifically unbalanced match than sit on the screen for 3 hours because the system is being too anal about skill ratings.
especially since the skill rating system isn't very good anyway and I tend to get steamrolled in "balanced" matches anyway.
