team balancing

Alright, so I'm silver III I believe, don't play ranked, just get placed so i can have the border. My question is, in my normal draft games why is the other team stacked with plats and diamonds while my team is all silver. Every. Single. Game. I feed every game, I lose every game, I know my mmr isn't the cause. I've been playing this game since the end of season 2, and it has never been this bad. Why are you guys letting the people that legit just play this game to have a good time get **** on? Why can't it be evenly balanced? This is why the player base is so toxic.
