As a veteran player, dungeons might feel "irrelevant", old, outdated content which nobody barely does anymore, when we have fractals and other open world content with their own map rewards. But for a new players, the dungeons usually are first experience of a "group oriented content" that they experience in the game.
As new players they rarely have understanding of the end game content and dungeons that they experience could have huge impact of how they perceive the game.
Dungeons haven't aged well, when it comes to old bugs or the rewards they give. Of course many older players might remember the old gold farming in dungeons before it was changed to the repeatable achievement gold reward we have today.
Do you think Arenanet should revitalize dungeons, so people would want to go there more often? Maybe update the bosses by reworking them from the scratch, introducing new combat mechanics what we have access now days in open world and raid content? Would that bring you as veteran player back more often to try dungeon path that you haven't done in a long time?
