I think you've got it backwards. SMN got quite a few major increases with the updates. All wards that were useful back then (which are very, very few) are still useful now, plus there's quite a few new wards. Inferno Howl is also one of the new ones, and despite what Malamasala said, it is still very useful. I am not aware of any COR equivalent of that, as I know next to nothing about the job, can someone tell me what exactly they meant? COR has an Enfire that deals up to 90 damage per hit and lasts for over 40min? Either way, my point is it's still very useful. It can increase a party's damage output significantly on certain mobs (for example, it almost doubles the damage output on the LB10 taru, making it an extremely easy win).
Fleet Wind was also added, again very useful, as is Earthen Armor. Before Abyssea, all SMN had was Hastega and Dream Shroud, the rest was hardly worthwhile. I've seen Aerial Armor and Earthen Ward used because of the long duration, but even that wasn't too useful and people did it more because of a "why not" attitude.
Also, BPs themselves were adjusted for the level cap increase (constant duration with up to 3min20s bonus from skill, which makes even Inferno Howl last over 4min, Hastega even over 6min), as well as a general perpetuation cost adjustment (lowered at some point during level cap increases).
