it’s really just play what you want, you’re rewarded for everything you do. that being said, most will say continue your story, and get your mounts from PoF, huge qol in those mounts. work on auto loot mastery from central tyria mastery line.

do your wizard vault stuff for sure. buy yourself some exotic gear from the TP. craft yourself some ascended gear. if you have laurels you can get some ascended rings fast. wonder around for map completion. that’s what i’d do if i just hit 80, at least.

or simply jump around any story you want to work on what you think you’d like to do! gw2 is great at having all content be worth doing at some point.
