Aside from doing all the blue quests asap, go aether current hunting in every region as fast as possible. Though the MSQ itself guides you through the regions nicely, not being able to fly is a royal pain in the butt for gatherers.

If you're into relics, you can do that as a sideline. Both ARR and HW require a good deal of poetics for some stages and you'll likely cap them multiple times before hitting 80, so it's a good poetic dump. Once at 80 you'll likely want to spent them on different things than old relics.


But I think that's about it, everything else has been mentioned.
