Something that has bothered me is that the tiering changes always fall in the middle of the month. This tends to mess up that month's stats, because half of the matches were played in one metagame, and the rest were played in the other. Obviously, this would not be a problem if the changes were made at the beginning/end of the month.
So my suggestion is simple. Could tiering changes be made at the beginnings of of monthly data collection periods? That way the monthly stats would be more accurate.
