Sabotaged Matchmaking

Im S5 however I am CONSTANTLY the only Silver on a Team of Bronze, which would be fine except the Enemy team will have SEVERAL Silvers if not an ENTIRE TEAM. What about this is even remotely fair? I try to keep a positive attitude but what player wouldn't tilt when being matched with players of Significantly lower skill. If someone could please explain to me How this makes sense please do. In the mean time i'm begging you riot, Fix the MMR system. Also, often times when i look @ my teammates profiles, they will be on a losing streak, when i look @ the enemy, WIN STREAKS. like really truly please god wtf.

PS When i played adc with my gold friends, they were SHOCKED to hear i was in silver because of how hard i was carrying (with competent teammates)
