Regarding the difficulty of the quest. Yes, you need to have relatively good gears, and people who know what to do in a party. Not any random group of people can do it. Its supposed to be a fun challenge for guilds, not a run-trough-quickly-to-get-the-reward quest. And from what I've seen of people trying it, so far they seem to think it is a fun quest.
That being said I don't think its as difficult as some of you make it out to be. People party in these dungeons all the time (except maybe the last one, but there has to be something in there to throw people off or its no fun). Try the quest yourselves instead of listening to rumors about it that may or may not be true.
