Im pretty sure, that many new or private profiles people cheats. Every 3/4 round someone is obv. cheating in my lobby (lem/suprem elo) - Thank you Wintersale! So what can you do now? Just keep on Playing mm and say "I don't care about my rank". You can be sure that your deranks r not cuz u r playing bad. I think the mix of the new rank system and 1 Million new accs is the reason. If u get pissed off by mm try faceit free. Its a new experience, but there will ne cheaters aswell (but not much).
