Logoffski used to be a serious problem in EVE Online. They solved it so that if you are engaged in combat and log out, your technically still online for a 5 or 10 minutes. Here, they should implement something similar, maybe after you get shot by someone within the last 5 minutes you are still in the game for 10 min if you suddenly log out.

There are many advantages to playing alone. In a group you have to worry about everyone else's well being. If a member is about to die of thirst while everyone else is fine, the whole group may chose to stop what they were doing and search for something to drink. It's also harder to stay sneaky when you are in a group. Generally, if you are playing alone avoid others as best as possible even if they state they are friendly.

There are consequences for player killing. If you kill a particularly vengeful player he may come after you, maybe with friends. Or possibly a do-gooder saw you slay someone and is willing to avenge the victim.
