There are plenty of details to discover inside the Black Temple. Such as huge statues just standing there.
We had a peek at Gurtogg Bloodboil just for fun after getting Teron down. There were too few healers in the raid to make a serious attempt so we just practiced without buffs and I think we got him to 60% or so...not sure about that number really. While clearing the trash to him this exchange took place regarding the mobs:
-Do they have any threat table?
-If they do they have no manners at it.
