I picked up a pair of these the other night, and they were a welcomed edition to my gear . Having come from a smaller guild, i was wearing ToV quested armor . While still decent, these were way better, and i was happy to get em. This zone however, is no cake walk. The sludgeworkers can whack hard, up to 1180 , and are not slowable. As a paladin , i found it hard to tank there without a really good cleric, and in some cases, a patch healer (shaman) to pick up the slack. GoD zones will definitly take some skill , and push groups to the limit that are not well equipped.
Oh, on a side note, when we initially zoned into the sewars, this fly conned white to me and was sittin in the first room you zone into, next to the doorway leading deeper in. Lucky us i guess:)
