Instead of forcing other players to go into wvw to achieve world competion
Keep the world completion within the same area of the game:pve.
But give players the option to focus on a specific part they enjoy to gain world competion.
Like complete all puzzles,or discover these places,search for holy grail,..
Some kind of graduation mission that starts once you complete all pve maps,that sends you back to specific locations..
Not making world completion easier,but allowing players to focus more on a specific aspect of world exploration that they enjoy
