Add a perk that either adds an extra generator at the start, or when the exit gates would have powered, they didn't because of the perk adding an extra gen. I know this seems sort of OP especially with ruin and the gen slowing perks, but I'm sure someone could find a workaround or adjustment to the perk idea.
I got into a game, went and started to do a gen, proceeded to get chased by a freddy. He downed me, put me on a hook and repeatedly hit the hook until I died. I looked on his profile to find that he has 100 hours, and he has 24 pages of negative comments saying that he only facecamps. Fun time imo.
