If Sombra is banned in 100% of games, that says a lot about how the player base feels about her.

In any PvP game, certain mechanics can suck the fun right out of the experience. Two major ones are stealth and control. Control includes things like stuns, freezes, or disabling abilities — basically anything that prevents you from defending yourself.
Stealth is similarly frustrating because it removes information — you can’t react or prepare for what you can’t see.
Designing a hero with both stealth and control is just bad for PvP gameplay. It creates an experience that feels unfair and unfun for opponents.
