Stupid droprate on Runestones has effectively allowed two of my alts to nearly catch up with my main....yes, that is right, by time the expantion finishes, I will likely have completed the questline 3 times....

They nerfed that one pretty heavily some point back. Any group of 3 people can pretty easily destroy him now. Provided at least one can tank (or has a pet that can tank), and one can heal (either as actual healer or hybrid offspec).
When I did it on my shaman, I just had a random Disc Priest who was willing to help come heal me, and nuked him down without much of a problem.
