I totally agree, FATES should give you at least 40k xp with the bonus, minimum. Each zone should have levequest that give you 30k exp to facilitate leveling up and exploration. And these 6 new dungeons need to give at least 6k-10k xp per kill with armory bonus. I think they are going with super conservative tone to stretch the basic content through 3 months before next patch which is understandable. Hot fixes probably coming soon in 2 months.
