There are millions of goals you can set yourself in GW2, and (if any at all) not many run really out of possible goals, only out of goals-of-interest. I did not played Gw2 this year, till last month, but now there were goals I was interested in again, so I spend 4 weeks on LS4 episodes (I got but did not played), the Warclaw and the skyscale, and now also some festival-achievements. So: play if something interest you, play something else (and come back later to have a look) if there is currently nothing.
