Diamond 5 tracer Gungeon N9XSM6

I've been struggling quite a bit when I entered diamond. I've played 2 games that felt really bad N9XSM6 this push game I was either getting cooked by their hanzo or reaper, this lijang game YEKTFP I was getting really pressured by their mei sym. I've been trying to work on my rotations the most. Any tips on how improve are appreciated
