Perhaps Gandalf, as I, has yet to meet the Hunter of Heroes? Not all of us have suffered enough to consider this as game-breaking as you.

No commander, pretender or mercenary in the hall of fame is safe. Without a mod to seriously nerf the hunter of heroes the early stages of a game make this bug more game_breaking.
Imagine losing your prophet or pretender on turn_5 because this bug caused the horror to appear and kill them. Imagine losing Hector and his heavy horsemen on turn_7 because this bug caused this nasty horror to kill Hector.

I guess some people have to personally experience the bug before understanding how serious the bug really can be during a game. Just a reminder that commanders even without a horror mark can be attacked.
