There is no point in proving the mmr system is crap.
MWO has a to small player base. 40k Players in 1 Month, that's not a lot. Barely makes it 4k Players a day, which is not enough for a decent MM. Therefore, (to reduce the waiting time) PGI has to put a wide range of players together in a match.
A lot of online games have this problem, nothing new. Nothing PGI could do about. Yeah, you could add a checkbox for my MM "I want fair matches and want to wait 30 minutes for a game", but I guess no one would use that on spending 5 minutes in a match..
You all can be glad MWO did not die yet, because of low player base (I have seen a lot good games die by now
