I must agree with Daomei. Plus, this is becoming a Wulfpack's hunt. Don't aim for a specific group, aim for a behavior. This happened; all right, how do we fix it?
Well the only possible fix I see is to chat with them when you see think they've gone, and leave the battlefield for more pleasant things you can do if they say they don't come back. Screen the conversation if you feel the need to. Keep a loose eye on the rounds while you do anything you like; come back if someone decides to kill NPCs. Ok, it's not an ideal situation, but it's better than standing there and/or forcing attacker to forfeit any attempt at surprise.
