I had to solo part of bfd on my rogue, for a ring, and could only take 3 mobs at the time if I spendt my cd's, and focus kicking on the healers -_-
Goal was that human pala or shamman thing wich drops nothing special, but was needed for the quest.
Took about an hour or so. After that I moved further in and got to the part right before the orc boss, but quittet there.. I think u need to be at least two man if u wanna kill that boss.. or some serious free time on u hand.
... or maby go shamman xD
