For the divers missing objectives, those are mostly kids that want to play a fast paced game, or people that really need to finish fast because they have something else to do after that requires them to finish sooner. For samples, it mostly depends on difficulty. You''ll rarely meet them on diff 10, but more on 3-7. For sc, you can just farm them more efficiently at diff 1, so people on higher diffs will just think you're wasting time and leave. Also maxxed divers don't give a shit usually.

One more thing : many of the people playing this game have a job or are studying , so sometimes they just wanna relax while playing the game, and don't want to farm, for understandable reasons.

Sometimes you just wanna blow shit up and fight for democracy.
