Because he ran back from the 1st boss location all the way to entrance and then sat, it will be seen as disruptive. A player who was moving and then suddenly stops moving, you could say shit happened in RL. The only thing--and mind you, I'm stretching as hell here-that I could think of that made the tank do what he did was he was trying to leave the dgn manually and something happened on his end. Again, stretching as hell here. I'm more inclined to believe he was trolling.
