The raids' story elementals felt like there was good reason to bother (I do enjoy the gameplay of wod's raids, mind you) and the threats were actually something to worry about. An army of swarthy Gnomes could have beaten the Iron Horde without any backup.
I guess if I had to pick a second then late Wrath simply because of ICC being a thing.
