This might show you the personal problem you have. You don't pay attention to the stories even heart activities have, let alone the stories around event chains. That means nothing will make you happy in this regard.
To directly respond to your comment, if you know where the areas are to kill "certain enemies" why is that a problem? You don't care what you kill. It's obvious you just want to mindlessly kill things over and over. I would try some other game if GW2 is too much thinking for you.
