"New game plus - quests will have no rewards..."

[Mhaeric]

Seeing how the MSQ skip has a giant Gold medal with the number 1 on it, I'm thinking not as many as you think. The story is good, but out of the millions of players, not many want to replay it for the sake of replaying it. If it gave XP I see people using it to lvl up other jobs.

Apples and oranges. Story skip lets people skip the lock on end game content that the story provides. People use story skip potions so they don't have to spend several weeks to months doing it just to play with their friends in end game. I'd argue that NG+ benefits people who used a story skip potion the most.
