Gaze into the heart of N'Zoth.
Soloing as a warlock.
Best chance of getting it done any time soon would be tanking the adds yourself with your pet tanking Nef. Again, if they're kited properly, they will deal very little damage and will fall over after 30 seconds. Obviously, its going to require more gear, but its not as impossible as you think.
So I just hit 90 this evening and to celebrate I decided to clear MC. I got the right binding from Garr, lol. In terms of gear I'm still in my blues/greens obtained from questing. How far can I get before I start hitting content that my gear just won't cut it?
