Take it real slow cuz since a lot of people you'll be playing with will have i90-i110 gear, you'll breeze through dungeons / content.
They nerfed a lot of the old 50 dungeons. Primals hm have echo now, and you have a lot of ways to gear up now easily via dungeons or trading in tomes.
So really, if you want content to last then i suggest you take it slow and easy and just enjoy the fresh 50 as later on you'll be joining us in the never ending forums of gear treadmills and "there's no content left.. So borrrrrred" . I still have a few more stuff to try/ do so i'm not worried about burning out fast.
