Because some people still expect to win simply by showing up. We tell them the game is hard, they think it's a wink-wink message that doesn't apply to them. We tell them the optional fights are the hardest (i.e. being a hero is a harsh business), they jump into every opportunity to be a hero because that's what they are used to - if the game offers you a fight, surely it's scaled to their level. It's not.
