The other problem with the MMR system is of people playing ranked a handful of people ontop of the smurfs do not belong in their elo. Typically someone is either worthy of being high gold/plat or higher or just being plain old bronze/silver.
People who climb will keep climbing over time and stomp all over their games. The game really boils down to who plays against the aspie and gets fed.
I.E, if you have two people in a bronze game on enemy teams both are high elo, but one gets stuck against someone playing safe who also counters them vs the other high elo fighting a dumbass who just feeds again and again, he will stomp on the game.
