I just want to climb SR, I have never played with a dedicated team before

I play most DPS, mainly genji, but I can do every hitscan very well expect widow, I tend to switch to the DPS the team needs but I normally don’t do call outs. I’m high plat, just dropped from 3018. Also a diamond tank and open que then a platinum support and when I play support it’s normally off healer, Lúcio, Zen ETC
