First of all - the screenshot does not break forum rules, for all of you saying to delete it, I suggest reading the forum rules. Naming & Shaming applies when you're actively trying to shame a player for bad behaviour, which this post isn't.
Secondly, Grades are not used for matchmaking OP and being that you are not a new player your MMR will be somewhere in the middle or higher, and will naturally settle when you've played a number of matches. Grades only show hours played this season and not the hidden MMR score. It also doesn't decay if you've been absent from the game for some time.
