Strong ADC looking for strong support main to jump out of silver back up to platinum!

Provisional matches put me in B5 (Probably because I never got to play ADC). I jumped out purely solo in a couple weeks and now I'm just playing my best role and have been killing it. My last few games have not updated on there yet, but I've gotten a pentakill in all of my last five games I believe. Last one ended in 17/2 (I THINK) I play Vayne/Graves (Mostly Vayne) I'm currently Silver V, almost Silver IV
