Just tested it, and firstly, I had a blast, it was so much fun, bearing the blunt of every mob that came down that path and living!
Threat wasn't an issue, so now is the long process of getting the gear so I can do the job better.
*note* I had a bit of troubles picking up the towering infernals, I did alrite and no one died, but I feel I could be more efficient, any tips, or suggestions for macro's.
I had a simple one;
/target towering inferno
/cast Exorcism (rank 6)
But it didn't work too well.
