I see.
I mean, I get things getting toxic because of fails in random DF with PUG style play, but with pre organized parties, I thought this kind of option would be more akin to endgame raiders where they are working towards being able to clear in a set amount of time. Or whatever else options to make it harder for some kind of reward.
Stuff like don’t avoid damage indicator equals instant death, or 1 party death equals a wipe and end of dungeon (no retry). I’m sure some people would eat that up, and I wouldn’t mind trying it out with friends.
