Matt, just to make sure that we are all on the same page - you guys do treat a "1 high Elo player + 1 low Elo player vs. 2 average Elo players" as poor Elo matching, right?
Technically the match maker will consider it a 'good' game if both teams were matched by having 1 high elo and 1 low elo player on both teams just as much as putting 2 average players on both teams.
The match maker can only work within the ranges given to it though and currently the ranges can be too large i.e. the matchmaker can drag in a high elo player to balance out a few low elo players, when we start to reduce the range what we should see is that the match maker will wait longer to create a 'good' game i.e it will have to wait for a player with a more average elo to show up (as the high elo player will be out of range). In the extreme case the match maker will simply give up and say it couldn't find a good game, this can potentially be seen as a good thing as you didn't want to play that game anyhow.
As mentioned we'll be monitoring carefully and we suspect we can tighten the ranges without having a dramatic impact on average wait times and failed matches, we can also adjust the timeout up from 2 minutes to compensate. Hopefully that answers your question.
