I think that it’s a good idea, but i would take a lot of effort to make that come to life because the best way to implement it would be to create a ton of them and then randomize them throughout the player base not to create zergs completing the same dailies, Theoretically it would be a good way to create a more “living world” as it would spread people in some empty maps and make the experience better for newer players / leveling alt characters.
I personnaly don’t think it’ll get implemented and here’s why: Arenanet has chosen living world updates over that kind of filler content. In another MMO where content gets more stale waiting for the next expansion for example, these kind of quests that re-uses already existing assets are perfect filler content. Although with the living world updates, Anet creates new maps (Silverwastes <3) where they want the community to work together towards a goal instead of splitting the community throughout the whole pre-existing content wich I also believe to be a better gaming experience.
