I really just want to be the best overwatch player I can be. I love the game and and want to feel a real competitive experience

I am currently ranked diamond 3 on tank, with a peak of masters 5 on this account. played xbox for years but after hitting t500 i transfered to pc which is not thew only place i play. I only queue ranked, but ranked is basically just qp at this point, so im looking for a more meaningful way to play the game. I play tank, specifically rein, hog and winston, but also play ram, mauga and dva if needed
