Lets think about this: You want to go fight a dragon? Setting aside the fact that it has a large mouth full of nasty, sharp pointy teeth, it outweighs you by about 4 tons, flies, and breathes fire. And you are going to pick up a sharp pointy stick and wrap yourself in a metal skin like some kind of TV Dinner waiting to be cooked? Of course you arent! But the king commands it. And all the other knights are watching. You have to do something.
