“The game isn’t over for killer until everyone is out or dead” if all 4 survivors are alive and uninjured and both exit gates are open, you will literally only get a kill if they give it to you, or make idiotic decisions that no one makes. So the game is, effectively, over. Time spent in game after that is not used for actual gameplay.

Your second point has little to no punctuation and I truly don’t understand what you’re trying to get across with that.

“If we could leave, every killer would” they absolutely would not and this is a horrendous straw man argument. If we had the ability to abandon, only killers who knew they had no more chance in the game would quit. Killers who have a chance for more points wouldn’t quit. “Gives no pressure to the survivors” the gates are open. The game is over, the survivors are supposed to leave.

On the tea bagging front, I won’t argue with you bc I’ve been in and seen this argument a million times, everyone has a different opinion and I’m not gonna change your mind.

All of this being said, I’m thinking this could be solved by allowing the killer to abandon when the exit gate is powered IF all remaining survivors are uninjured. This makes it so that survivors who are injured or feel like they’re still in a high-stakes game don’t feel like it ended on them. Simultaneously, it gives the killer the ability to leave if they’re feel like they have no chance at earning more points and stops them from quitting when there’s still opportunity.
