It's not registering. C5 bambur defending on a hill tile wont protect damaged siege from free kills. Acheron lets 3 strength warriors take the hits when the odds are still reading <.01%. The defense oriented heroes are absolutely worthless like this, you can't protect anything from them. The enemy just gets to happily chew through your army. Is it intentional that they don't defend against even near 100% odds? I like that rosier no longer gets owned every time someone follows him back home and gets lucky, but it's self defeating to use maros and have even the adepts die before he takes an easy hit.
