Description of the match / things you want reviewed:
Nothing in particular, just a random match for general advice and tips. I do think I misuse her ult a bit sometimes and I could've switched when getting countered by Doomfist.
I know stats aren't everything, but I do usually have the most kills and fewest deaths.
