Yeah actually I have a problem with this quest... I mean come on! Turn back into a Warewolf you gimp! And right at the end when hoards of them are chasing me around the buriel chamber where is he? Has he turned into a Warewolf? No! He's down on one knee again! Farkas you Farking Farker!
you got chased around the chamber? Farkas and myself seemed to have it just fine... my problem is that followers/npc companions don't sneak, can't avoid traps, get distracted and aren't where you need them and are never at your level... so I tend to leave them home unless I don't get to choose.
I've found that followers and npc companions are good for holding one or two of the mobs for me while I clear the room and then I can take what they have on them. If they go to one knee I guess you can be glad he isn't dead, right? Rescue him and roll your eyes when he asks if he can come with you later.
