I have lost every game since patch 5.6

Apparently I'm in gold 4... Well I was now I'm barely staying in gold 5. I used to win maybe 50% of my games but this is rediculous. The problem is that I can't carry games hard enough I guess. I think that since we hit season 6 the game in general is won or lost in champion select and the skill gap is becoming closer and closer to champion select rather than a players ability to outplay or itemize. I see the same thing every game.... Group mid and whoever seige harder wins. There are no more backdoor there are no more baron fights... It's just one big 5v5 mid and whoever wins wins the game. This is bullshit
