There is currently no way to re-acquire campaign questlines in Destiny 2. It is true that specific campaign missions are re-playable, but the questlines that guided you through them, provided dialogue and offered the whole story are not obtainable again after you've completed it for the first time. The addition I am proposing is to add these questlines as permanently re obtainable either back to Amanda Holliday with the return of the first 4 vaulted campaigns, or to simply place these questlines into the pre-existing kiosk sat directly to the left of the post master in the tower. I think this would be a good addition to the game as it provides players the option to fully replay their favorite campaigns on the same character if they wish to do so. Today, if someone has fully completed all of the campaigns on a character, the only way to fully experience these campaigns again is to create a new character. This is especially a problem for those of us who have completed every campaign on all 3 available character slots. In conclusion, adding re-obtainable campaign questlines to Amanda Holliday(Not currently alive) or the quest archive Kiosk posted directly to the left of the post master in the tower would offer players a way to fully replay their favorite campaigns without needing to create a new character, profile, or join a friend for their first experience. I hope the community can hold a similar sentiment on this topic! Let me know what you guys think!
