I tried playing with some friends of mine...
And the resulting losses seem to have dropped my MMR down into bronze territory again. I got demoted 3 ranks down to silver IV as well.
I just won a 35 minute game in which there was not a single teamfight. Everyone just wandered around dying the whole time. Our Graves jungle missed every single ult he fired. Not even an exaggeration, he and I kept talking about it.
Congratulations Riot, you've forced me into this with your new queue. Playing with friends has completely destroyed my competitiveness, and it's downright enjoyable. You disgust me.
