Just did this last night after multiple attempts. Seems a little difficult for a level 37 quest, at least compared to other fellowship quests of similar level.
In our group, we had 3 wardens (36, 40 and 43), champion (40), minstrel (39) and a guardian (60).
A previous attempt with a different group the previous night (and a lv 60 minstrel) resulted in a wipe.
This group went well, b/c everyone stuck together and listened for the most part...plus, the 60 guard pulled the stuff in the tent (no aggro).
We did have a couple times in the tent when we had about 5 mobs at once, but we had enough tankage to handle it. I think we had a death or two, but they managed to revive back.
Very tough quest, since the tent is ridiculous for aggro and there are at least 3 groups of mobs, plus the ones at the entrance and random wanderers. I'm just glad it's done, as the has been by far the most difficult quest I've encountered thus far.
