I didn't think it was "you" more like "someone must do X to save the world."
I would NEVER have a prophecy that needed a specific person.
Still, same basic reaction,
especially if "others are trying and failing". Why would our party stand a chance in this circumstance???
As a GM, I avoid these things like the railroading plague that they are. I use megaplots, but NEVER "one path, one small group, can stop this thing" plots.
If the party ignores the megaplot, they're going to get killed along with everyone else who gets caught in it.
If they're avoiding it because they don't know what to do, then it's time to pull out the Friend/Ally/Patron card. Not some random unknown joker who ropes them in out of the blue, but a friend or past acquaintence who asks if they can do certain tasks along the road to resolving the megaplot. They can always refuse. If the party is only interested in the side plots and minor actions, then the Ally who runs the show gets the glory. If the party shows interest in following the major plots and taking charge, then they will get an opportunity to run the show and get the glory.
OR....The problem is resolved by others. Period. And thus the party gets none of the glory. Heck, depending on their actions, they may gain a reputation as cowards or selfish jerks.
