Plat V ADC/Support Main Looking For Plat-Diamond Team

I prefer to play ADC or Support as I feel I am the best on these roles although I'm also good on a majority of assassins and a few mages. I'd like to join a Ranked 5's team but I'm also open to join a team for ranked 3's team.

For ADC my best champs are Jinx, Ezreal & Caitlyn.

For Supp I'm best on Thresh, Leona & Sona.

My varying champ pool includes Katarina, Morgana, Annie, Akali, Zed, Fizz, Orianna, Lissandra, Ziggs & Vladmir.
