this post is about the patent link, that has been posted around the forums many times and various people claiming it's a proof that MM is rigged.
First and foremost, PLEASE stop sending me this link, in last 7 days or so, I have recieved around 50 PM's or mails with this "news".
Second: I believe that this patent (while it describes a possibility of how MM could look - the point of this is to make the patent as broad as possible, encompassing every possibility - this is a common practice in intelectual property law) is by no means any proof that MM is rigged against good players. It's simply an option, that shows Wargaming was thinking about this.
Personally, I can't judge, simply because I am not a good enough player to be affected by any such "rigs", but I doubt there is any such rigged MM implemented.
