Why do Some Argue Against Skill Based MM?

DeviouslyCursed: Let me try explaining why Random MM is awesome this way: Random MM gives all players the same 14 vs 15 battles over time. We all get really good ones in our favor. We all get really bad ones not in our favor. Most of them fall in the middle. I view this as a trial. The Random MM is giving everyone a wide set of skill match ups, variations, tank differences, etc. Then each player gets to see what they can do with it. It is a dynamic, ever changing thing; you never know what you are going to have to face. This adds much need variety, and this alone is what allows players to stand out. If your 14 teammates average skill is slight worse then the enemy 15 players, can you over come that? If so, good on you, you get to win that match up when others can't.  What about if they are fairly worse than the enemy? And so on. Of course, this means there may be some 14 v 15 matchups that no player will be able to win consistently when put in there (and some matchups that no one will lose consistently either). It's not just about losing or winning that one really stacked against you battle either. It's about how many of those you can pull off over time. But it has to be this way if you really want to see where players stand. You'll never find out how high people can jump if everyone can touch the ceiling.
