I'm not going to pretend that MM is alright, because it's not. But, for some reason, the change on game modes seems to have made things even worse in this matter. So, we'll do this once again to get HiRez-senpai to notice us once more.
You know the drill. DO NOT POST COMPLAINTS, KEEP THEM ON RANT THREAD. Post EVIDENCES and proof that Matchmaker is malfunctioning.
Piece of useful information on how MM is supposed to work:
Unranked, Bronze, Silver and Gold tend to fall together on the same ranked match. Broader than this is not supposed to happen.
Platinum players are prone to having Gold, Platinum and Diamonds in their team and on the other side. Any range bigger than this is not meant to happen.
Masters are one tier above. They should be paired up and against Masters and Grandmasters, rarely diamonds.
Ranked Borders have zero effect on Casual standings. That Grandmaster who fought against you on casual might simply be someone who doesn't play casual too often
Different game modes =/= different matchmakers.
Matchmaker considers Win Rate. "Oh, but my elo on Guru!". Matchmaker does not consider elo, be it guru, masterpaladins, Wallachia Elo or anything.
If you have any screencaps contradicting the information above, post them HERE, for they are NOT supposed to happen AT ALL. I'll send this link to HiRez so they can see and explain us what's going on. Clearly, the Matchmaker FAQ is no longer applicable for some of those stuff.
Let's go!
