I'm not sure I agree with this, for most other games, fine, being a good player and working with the team all that. But here you are supposed to be criminals, Los Santos should be a wretched hive of scum and villainy. Nobody should play fair, and if screwing over your crew nets you some sort of gain, then why not, because that's what criminals do. Of course on the other side of the coin, if someone has done you wrong and you want to take revenge on them by making their life a living hell, that's also fine. It's a game world populated by criminals, the idea of an entire online component dedicated to complete and utter chaos sound gloriously brilliant. But I'm guessing most people won't see it that way.
There may be no I in team, but there is certainly an M and an E.
You know, Hitler wasn't all bad, after all, he did kill Hitler.
