I agree about adding in more game content into GW2. What I would like to see is more dungeons, plus to have the difficulty level brought down so that you are not dieing in them contently. The repairs cost too much to be dieing like that all the time in dungeons
Also I would like to see better cash rewards at level 80. For a level 80 quest to only give 3 silver at completion is disappointing I would also like to see better drops from the dragons. GW2 looks awesome, I love how the combat system is, better then other MMOs, but what I look for in MMOs are goals to achieve. GW2 is lacking in goals.
