The march to Outland Loremaster continues after finishing up Blade’s Edge. In case you, too, are having trouble with Blade’s Edge Loremaster: wait until 70 (if you’re not) and then come back and do Ogri’la and Shatari Skyguard stuff. That should get you there.
This means I have three zones left: Nagrand, Netherstorm, and Shadowmoon Valley. Nagrand is by far the most difficult zone for Loremaster so far. With most of the other zones I’ve done, you’d finish up all the quest hubs and have maybe four or five hidden quests to track down. With Nagrand I have, like, 16 hidden quests to track down.
Never fear: I’ll figure it out and then pass all the juicy details along, to anyone out there who’s interested!
