can i just get close to equal skilled teammates? close???

facing all golds and plats im diamond none of my teammates have ever played ranked. Is my mmr that high that im god? Not one game today ive had a fair fucking game and ive been playing since 6pm. Whats the fun of being diamond if im played with bronze 5 teammates every game anyways? I have to actually play ranked so i can get a tiny bit near my skill level. fucking unreal. when i diamond is matched up with such bad players that he is super fed every game while all 4 players feed their asses off we have a problem in the system
