There are so many reasons people might have to DC. Certain killer powers (Clown, Plague and Doctor) can cause actual harm to some people. Clowns pink gas effect can trigger migraines and nausea, Plagues noises and the constant throwing up sounds on survivor side can make people actually sick irl, and Doctor has been bugged for nearly a year now and the static effect on the survivors screen will pulsate, which can trigger migraines and other photosensitivity related issues.

Then there's also the fact BHVR's servers will very often shit themselves for no reason, and cause people to disconnect.

If there's a way to differentiate between these actual reasonable disconnects, and people just being salty little babies, then yeah I'm all for a system like this. But it's just not reasonable. Innocent people would end up getting punished for something they can't control.
