I don't know if I'm serious about this idea or not. It's a bit silly.

For all the people who just want to see the story for difficult content, here's a suggestion to allow exactly that: let them just see the story, in game. Second hand.

Have an NPC (wandering minstrel?) that will show them fake little sports-montages of the fights, and the cutscenes, both featuring players that have actually beaten the content. Perhaps the server first(s), or the current record time holder(s) (reset weekly). The NPC could interject now and then with reminders that they're relating the tale as they heard it. Obviously, any given story would only be available once it's been beaten on that server (and maybe only a certain amount of time afterward; the story's got to get around, after all).

At the end, have the NPC lavish the heroes of the story with praise, and encourage the listener/watcher to strive to reach their level of greatness, or what-have-you.
