[Dev question] Do you know about the player devision in palace of the dead?

I do not think it is SE's goal to have a DF where one way of playing pushes people out to not playing completely

Have you considered that they have the fixed party option in place as a possible counter?

You can either run DF and take a chance at getting a group whose goals are inline with yours, or run fixed and guarantee your party's goals are inline with yours.

They even designed it such that you don't need a full party, or even set roles. (up until a certain point, but that point isn't really until after floor 100.

Honestly, it sounds like you want to punish players for not playing the way you want them to, instead of using the tools already available to you to make sure you're playing with a group that has like-minded goals...and that's only ever going to lead to conflict for you.
