What do you think? What's your preference? Do you like being saved?
No, I don't like it. In my game last week, the heroes and their allies were all down except one in an arena fight. My solution when the last hero still attacked the obvious leader of the opposition and wounded him was that all the other enemies withdrew to see how the one-on-one fight for supremacy played out. After a tense battle, the hero eventually prevailed. Then he was able to escape with the other unconscious hero but the allies got left behind. So, they survived but there was a price. It was close and hopefully more satisfying than some outside force coming in to save them.
