Duo Partner?

So i'm an adc main who is looking for a duo support main. That likes to play tanky champs or champs that have cc. I was at s4 at the end of the season 6 but i was placed in bronze 1 in flex but flex as a lot of problems and plus i had lots of afks. but anyway i main ashe, cait, mf, jinx, jhin and sivir mostly. I'm trying to expand my champs. I believe and a couple of other people have told me i deserve to be gold but i just can't seem to make it there. If interested please reply to this post :P.
