Waiting for hatch incentivizes survivors to break the rules and hold the game hostage
Hiding and making no attempt to finish generators while Endgame Collapse cannot be started is against the rules. This is not about being chased off. This is about not trying to repair at all. Survivors are required to attempt to repair. This is not up for debate.
Hatch requires only one survivor to be remaining in the trial, because multiple survivors being able to escape without finishing their objective rewards failure.
In situations such as two survivors are dead and the generators are not finished, or when survivors end up in a 3-gen situation, this incentivizes breaking rules by hiding and doing nothing till the others die for a chance at the hatch. This is a fundamental design issue that needs to be addressed.

They'd have to do it the way Blizzard is doing OW, because there is no way you can convince anyone to buy the killers over again. Even if they wanted to go that route, I don't think it is in the cards for them. Then again... if they took a 3 year break from updates like OW did, I suppose they could make it happen.
God, imagine having to rebuy characters and re-grind out progress LMAO
Stalemate situations are definitely a problem right now. Idk how to fix it but it needs to be addressed. Maybe they could add like a 30 minute timer per match to prevent this sort of thing.
An idea I had was reworking the AFK crow system to make it impossible to hide doing nothing for extended periods of time.
