The best method to counter and I've seen this work very well in other games is as follows: 1) Alt-4 or any other insta disconnect should keep your character in game for at least 60 seconds. 2) If you're in combat, you cannot gracefully disconnect for "x" amount of minutes 3) To gracefully log out, you must not be in combat and select logout which initiates a logout timer of 15 seconds. If you enter combat within that 15 seconds, the graceful log out timer resets back to 15 seconds and does not start again until you are out of combat. In my opinion, Disconnecting to avoid pvp in a pvp game is as much of a cheat as any of the script kiddies.
