Holy Moley!

Man season 7 has not been kind to me, every season I just play goof around get to gold and call it a day. So far this season, I've done the same exact thing but gone from silver 1 to silver 5. Even my most played champs have negative win rates now. It's crazy I just play poorly most games and when I finally get something going someone either afk's or just decides to quit or the game is to hard for me to carry. Did season seven change so much that and I just haven't figured it out or what?!
