I was only able to turn in Netherwing and Skettis before getting summoned, but the quest xp is as expected in my previous post. This is about 91k, plus maybe 6k for discovering the new zone (summoned before I could take a “raw” xp screenshot).
p.s. questing in the new zone works best. Completing the Utgarde Keep instance (2 quests) got me 64k+, and all the mobs’ xp of course.
