The best thing I liked about Guildwars 2 was the World vs World PvP game and the Pve world events. When fractals were added I started playing the game less due to feeling forced to do the thing I hate in MMO's. Run the same dungeons over and over.
This video though shows that they are swinging back away from closed 5 man dungeons back to massive world events.
Dungeons do get a update to make them more enjoyable but give me more great out door boss fights like Jormarg
