It's also worth point out that this is a multiplayer cooperative game. A truly considerate person who was just looking for a leisurely pastime without any pressure to perform would be better off finding a single-player game in which their under-performance doesn't adversely affect the team's experience. That's like playing on a soccer team for fun, but not putting in full effort and being surprised and/or hurt when your coach and teammates are disappointed in you and tell you to do better. Sure, it's a game and its only for fun, but your team is still relying on you and there's an implicit assumption that you signed up to give your best effort.
