How to deal with non contributing players

[OurMom]

Because you make PotD/HoH 33% harder without a 4th player.

Can't speak for HoH but for PoTD that is absolutely not true unless you all are close to the worst players in this game. I practically live in potd and have to kick 1-2 other people and ended up trioing or duoing the place just fine. If you guys are that bad where losing one player sets you back, that's not the game nor the community, that's you.

It's not reasonable to ask parties to "not open chests" when they aren't at 99/99,

Good thing I specifically mentioned killing everything and getting poms and nothing about those silver chest for a non capped player
