Did you consider the fact there's not enough players? It's already prioritized that the match ups will be as close to your level as possible but if there isn't enough players, it has to go down.
I wouldn't mind this if their was enough of a player base that it wouldn't affect wait times but that isn't the case. We already have to wait longer to find matches thanks to the newest change they made and doing this will only make that wait worse so not supported.
