1. Giving people a ban from using LFD because other players voted them out is toxic and cannot work.
2. This could work, except then the goal would be to just leave the key at the first sign of adversity so that it doesn't depelete, probably resulting in more wasted time than before.
3. I don't even know what you mean here, tbh.
4. I agree with this, except for that if one person wants to forfeit and the other 4 don't, then what?
