Back after a while, what have I missed?
There’s nothing that you need to do or need to get. Your characters should still be fine in whatever gear they were wearing. As far as what you’ve missed…you’ve missed a whole lot. Best if you just log in and start playing.

As you can see, far too much to cover.
However, if you want the latest bling, you need to get ascended gear/legendary. Start collecting laurels for your trinkets and get your crafting upto 500 for acsended gear.
Its basically a big expansive, grind that’s designed to take you 100’s/1,000’s of hours. In the meantime they will add more grind to keep you playing…
There’s a ton more grind, from living story, to crafting, to even things like post-nerf karma.
You’re going to want ascended weapons/trinkets to remain competitive.
