It looks like these guys will actually be the pet that will fight with the wolf for the hunter's main choice when raiding.
Demoralizing Screech: The attack power reduction from this ability has been increased by 40%, equaling the maximum possible attack power reduction from the abilities of other classes.
Demoralizing Screech now decreases the melee AP of all enemies in melee range by 574 (Up from 410). Lower ranks increased accordingly.
This means that if you don't have a fury warrior or feral druid in your group who may or may not remember to keep Improved Demoralizing Shout or "Improved Demoralizing Roar" up, you are still golden.
I suppose this will proved to be most valuable in 10 mans. I hope you don't run into issues in 25 mans where you don't have someone else covering the improved Demoralizing X debuff.
