Why me Riot

I love league of legends it is a fun game but what really kills it for me is when i play Ranked 9/10 my team feeds and there is no way of me ever wining. I feel like i get placed with bronze 5 teamates then i face gold 1 teamates. Why does LP have to be counted when u win games why cant it be when u play team friendly and do good like placing wards being in team fights getting assist because all of my teamates say "Mid or feed" or "Top or Feed" its not fair then i have to dodge that game then i get penalized. And at the end of a game if a guy was refusing to do anything but troll all we can do is report but all it does is give warnings. I really wish i could play league for long periods of time but i cant, 2 games is my max before i start to get headaches. I wish one day riot will fix this some people might not have a problem with this but i know a good amount of people who have my same problem.
