If you suddenly quit a rated match, Valve will punish you with time-wasting purgatory. Some people pay money to have others help them leave purgatory.
The difference is when it does happens, it drags out longer, but it is less common.
My experiences in overwatch weren't any good either. I remember the match that made me stop playing very well too. We lost, but I had gold in every category with my two friends taking silver and bronze. Essentially, the other two people weren't playing well at all and started spouting the most toxic shit I had heard in a long while. I guess fuck us because we were just playing for fun and still managed to do better than them? Like it wasn't a blowout or anything either.
I just don't understand some people I guess. Your post managed to bring that memory and reminded me why I don't play competitive games anymore lol. There are plenty of toxic players out there, but in my experience, a lot of them are pretty bad and are most likely projecting.
No, but there is a term for that too, "smurfing".
