Nope, no courteous people in this game. All joking aside. The problem is that you notice or remember the ones that were asshats. The ones that weren't just slide on by. So unless someone is actually vocal in helping you, you will most likely only remember the bad people.

That being said, courteous is somewhat of a subjective term right? Depends on what criteria you hold people to when you move them into categories. Plenty of people are pretty mute when they play this game, but that doesn't mean they are courteous or they're rude. I find that this game has more mute players than anything.

However between what I encounter more; courteous players as opposed to dicks. I meet more dicks.

Unless you meant player courtesies to be something else.
