So I expect them to care? No. Do I expect them to go full on troll mode if half the lobby (their team and enemy team) is saying it’s unfun? Unfortunately, yes.
That’s the problem. It’s not that I expect them to express concern. However, I don’t think it’s much to ask that if a player is actively engaging in cancerous behavior, that they stop.
Instead what happens is exactly what you’d expect from a Sombra player: they double down on the behavior and do everything they can within the confines of the game to brag about said behavior for no reason other than because they know it’ll annoy a lot of people.
