The game would become unplayable if it was lol.

with the right perks or hook distance offerings and you could just hold a game hostage indefinitely if you wanted to, the killer would be unable to hook anyone unless you let them.

They might just run unbreakable as well, so the first slug they will recover from, and after that all it takes is a survivor tap to pick someone up, so they would have to camp each body individually, and the match would go on for an eternity and just result in pure salt in the post game chat.

Also with tenacity they can move around too, so they have to camp and move and pay attention to directions the crawling person shifts too- lose track for even a moment and baaaack up they go.

Edit: Oh and I almost forgot tenacity + Head On, they will craw to lockers and try and hang out there too, and just like, locker stun you and then pick them up and between all of them running it they can do that endlessly.
