Q:
Am i doing it wrong ?
A:
Same thing happens to most. Go to one of the other starting areas to catch up. In your hero screen, click the pvp tab and Go To heart of the mists. You can get to the other areas from there through portals.
Oh and be sure you complete each area 100% before moving on. And gather all crafting materials as it give a lot of exp.
Aside from the heart NPC’s, dynamic world events can also be a factor. It can be slightly random depending on the amount of dynamic events that you encounter and maybe that’s one reason why you are underlevelled.
You can also do other things such as try for map completion as it gives a sizable amount of XP and even crafting.
The daily achievements also contribute to the XP.
These are what I can think about at the top of my head.
Best thing you can do since you cannot simply pick up a quest and complete it is find a large group of people. They probably know a nice rotation of Dynamic Events thats actually worth participating in.
thanks for the answers, much appreciated!!
