Tanked MMR should not warrant...
Pairing low silvers with Platinums. Yes, I have poor MMR due to shitty matchmaking (afks constantly), but how in God's name am I expected to carry people who are nowhere near my level of play when they are facing people 10x better than them. (Yes, Silver 3's facing Gold 2's-Plat 4's? Nty)
It is actually baffling that your system believes that a Platinum player, who goes on a loss streak, has suddenly became the level of a Silver player and therefore unfairly places people who aren't the level of Platinum or around in my games in order to manipulate the matches to support what your system believes.
