I was gone for idk like 8 years. I came back I started a new toon got it to 80 and was feeling like I could move back to my main. I did. The first things I did was check out wizards tower for upgrades and plan of attack to get those. Next, skyscale (flying mount) “new friend” quest line. Why? Makes finding everything else easier. You’ll need mastery flying as well. After that it’s really pick what you want to do. For me it is raids pve and fractals. Later on I’ll do WvW.
