What is the obsession with MMR? I have around 1300+ games played and i have played 2 ranked matches. Honestly, they're stressful as hell and i don't have fun!
I thoroughly enjoy playing for fun with friends and if we lose - so be it. It's DOTA, you're going to get at least one moron on your team that messes it up.
I dunno, maybe it's just me...
