Nothing special about this instance. It's grinding heaven though - no annoying trash mobs and only dps bosses with one minor exception that just requires some extra healing. Not much fun to view I think, since it's pretty much just dps-bosses, but the positioning on the first fight is worth noticing - it's a good way to catch the adds once they come.
