There will always be losers in the Metagame that defines high-tier play- that’s what a Metagame is.
It’s why GOATs happened, it’s why Mirror-Matches happen, and it’s why heroes like Sym have never happened outside of gimmicky teleport plays.
Sombra probably wouldn’t see play even if she was “good” because there are other options that play the meta better.
May as well make the game more fun for everyone else.
