That sorta happened in the community VIP (SAC Attack) with the second way to win. As the VIP, you had to kill the other VIP twice, and each escort once to win. If you killed the VIP twice and one escort, the other escort suddenly becomes the prime target for your VIP, making it a second, lesser VIP. Especially if you still had to kill the VIP two more times to win. It was interesting and fun to see a sudden shift in combat when an escort became the new 'VIP'. At times, there would be one kill left on the VIP, and one escort left to be killed by your VIP. Two ways to win. Those became very hectic, especially if it was tied on both sides.
Good times.
