Double post since I'm on mobile, but this also assumes that the tank isn't in on it. The tank can easily spin the boss on purpose to cleave the damage dealers as well, and if a tank and healer queued together under such a system, I honestly can't see anything but pain for whatever DPS have the unfortunate luck to be paired up with them. Pardon if I come off too strongly, but I strongly disagree with any kind of system that can be used to sabotage.
