Wrath had a level of accessibility coupled with a popular lore figure to suck people in. I seriously think they need to bring back wrath style 10 mans, even as a parallel to current 10 mans if need be. Puggable raids are the only thing missing between wrath, cata and mop. LFR is fine but it really is playing the game on easy, and noone feels good doing that. Bring Illidan in on a new burning crusade and let us 10 man the stuff, add a 5 man during a raid patch.
