I haven’t had a chance to run these yet (still 61 sadly) but for those of you that are having issues I found some good ideas and tactics on the Warden boards for this instance. Sword halls is the 3 man instance, and since all the instances drop the same radiance armor piece barter items it is worthwhile figuring one out and farming it. I’m not going to post them here in case folks want to figure them out themselves, but if you want the spoiler check out this link.
However, I will point out that I like the fact that in this thread there are multiple strategies that work and pretty dramatically different group make-ups.
