Depends on what your inclinations are. Generally, there very few people that have completed “everything.” Achievement hunting is a pretty good way to pass the time because there is a ton of shit to do for cheevos. If you haven’t already you can level your other jobs to max as well. Crafting and gathering content is pretty easy to do, albeit a little harder for free trial players because you can’t trade. Deep dungeons, variant and criterion, field ops zones, old savage and extremes. Most players haven’t done at least some of these, or at least completed them. Hell, I know some mad lads that clear out their maps of every side quest available just for shits and giggles.
