AFK-ERS AND FEEDERS

Hi i play 4 years this game and i really enjoy it... But... In enjoy when i can really play good games even if i lose... Playing good game requires good teammates that really try hard to win or play properly!!! In the previous season i was Gold V... When i played my promotional games i had 6 wins 4 defeats and the game placed me and Bronze II. I had to fight hard to climb at Silver V and i stayed there for for 2 months cause i couldnt promote cause of bad teammates... Finally i got some good teams and i managed to climb and Silver II !!! Then bad teammates showed up and i was demoted to Silver III, then i got Silver II and back to Silver III and now Silver IV....... I really play really good in most of my games but at 8 to 9 games at least, i will always have an afk-er or a really huge feeder in my team (like 2-14-6) or guys that just troll pick because they got autofill or beacuse the died 1 or 2 times at the 1st 10 minutes blaming his teammates.... Most of the feeders are not just having a bad game... Its that they really dont know how to play this game properly or big time troll for various reasons.... I really cant carry games when at 8 to 10 games i get such bad teammates or afk-ers even if i have good scores like 14-4-8........ I have spent at least 250 euros for this game cause i really like it but seriously getting such bad teams for most of the games makes tired and icapapble of playing good because i just had enough....!!! I would really like to know if u can do something to help me...!!!

Thank you!!!!!!!
