1: What I'm trying to tell you is that the points that are given to everyone at the end of the game are the same for everyone. They're the sum of the point totals of all players, along with some miscellaneous extras like survival medals and killstreak medals. Unless grinding a challenge has become that desperate for you, you're not losing a significant amount of points towards that challenge.

7: I know cases where players get annoyed with other players that aren't helpful. They will outright refuse to help them because the lone wolfs are not helping the team.
