To climd the ranks

Im high Platinum, staying around 2750 sr. I typically play D.V.A, but I have experience playing mercy, zenyatta, moira, lucio, and ana on hanomura point b defense. Other tanks I can play would be reinhardt, orisa, wrecking ball, and zarya. I am only 14 so i have school and i might not be as active as most think. If needed for stalling i could play mei or tracer.
