It’s like no one in pubs wants to go past round 21

Every time the exfil comes up around 20-21, people are done and just want to exfil. Only a few games where randoms want to keep going. I can’t even get to a tier 3 pack a punch because everyone is already done. Has anyone else been dealing with this? At this point I might just start doing the Easter egg steps to try and get randoms to stay longer. At the end of the day, I believe the charm of this game mode is the bare bones of “How long can you last?” Even if not doing the Easter egg, challenges, or speed runs. The question of how high of a round you can go seems to be lost. Of course I could play solo, find a dedicated group, but there is a uniqueness of just jumping into a lobby of random people and seeing how far we can get to.
