The matching algorithm seems to have been updated, and the update isn't an improvement. Until the past few days if I joined the 3-player queue only and there were eight more so people in it (counting # in queue minus # looking for practice games, since I'm only looking for a rated game) I'd match in a minute or two. Lately even with ten or more by that count, I haven't been matching after even a five or ten minute wait.
The 2-player queue seems slower, too, but not as drastically as the 3-player. If there was a change, change it back, please.
