Just soloed him as a 70 Shadow Priest. I spent about a half hour looking for a partner to do this quest, and then tried soloing one of the other mobs around him. It went well, so I checked here and someone had said that if you could solo one of those mobs, you could solo Cragskaar. This is definitely the case. He was immune to fear, but the tiny little caster pushback fiends he summons are not.
If you're a shadow priest, I had about 738 spell damage. It's possible to solo this with less than that even, seeing as I was still pretty close to full health when I finished and that I killed his little adds afterwards just to show off (making sure to shield when CD was up, and to use my improved vampiric embrace.)
