Actually the first thing is go over the patch notes to find out which PVE activity will have the best crystal-to-effort ratio. Then I'm gonna do the solo quest(s) and explore the place.
Afterwards, start farming crystals and complete the plunder skulls party.
I will check out the new locations, but I won't start questing right away, because I still haven't finished all the quests in Vvardenfell (plus, although I'm always exited about new content, it can also get a bit overwhelming sometimes ). Then I'll do some dungeons and see if I can collect enough crystals to transmute a weapon or two.
