No, hostility in the context of playing the game is fine. Its a PvP game so that wouldn't be a tenable policy. You can go and kill the other team all you want

No, hostility in the context of playing the game is fine. Its a PvP game so that wouldn't be a tenable policy. You can go and kill the other team all you want. Poor behavior in the in-game chat or metagame is whats at issue here: sending other people messages to insult them, throwing matches on purpose to "get back" at your team, being a poor sport, etc. Edit: Here's an analogy. Consider if you were playing a basketball game and one of the players slapped the ball out of his teammate's hand and started screaming in his face about how he s a terrible player and should have been aborted. That's the sort of behavior we're talking about.
