See, what I don't understand is why the system makes ridiculous assumptions.
For example, if I go on a 4 game win streak, the system assumes I am actually higher skilled than my rank, and thus my MMR is high. Then the system will pair me with higher ranked opponents to see if I can win that. At least, this is how I understand it.
My question is: Since when does a small winstreak automatically make me a tier higher? This is why the system seems stupid to me. Why am I punished for actually winning games?
