It's nice they added a scalp for the nightborne, they needed it. Now if they could only get around doing it for female night elves DKs using the 3 DK only hair colours. They'd been scalpless for a decade...
I found an orgrimmar portal in Thunder Totem on my worgen alt and immediately died... had to get res sickness as I couldn't stay alive long enough to hearth!
I think the nightborne rep portion is easy. The quest line for the nightborne is no longer rep gated. Doing the quests will get you to exhausted.
