All I want to do is play

I think that normals and Ranked should be completely separate. There are so many people who only play their provisionals because they want to stop getting matched up with unranked trolls. The algorithms in LoL's ranking/provisional system places you with better players based on your rank in the past season. For people trying to start out from unranked, they get matched up with bronze and unranked players. If you happen to get unlucky, and your teammates are trolls, you get placed in Bronze. You then say "ranked is stupid" which leads you back to normals, but when you go back to normals, you are matched with the same idiots you find in your ranked matches. Lets just say you are ambitious and try to play ranked to get up to a higher ELO. The question is, HOW ARE YOU SUPPOSED TO GET OUT OF BRONZE IF YOU GO 13/2/4 IN TOP LANE AND YOUR ADC GOES 0/12/2?? What you just read is my life.

TL;DR: Im stuck in Bronze because my provisionals went bad and now I get feeders and trolls in both normals and Ranked. I can't carry that. PLEASE HELP!
