This "Stampede" ability is one that the hunter community has been requesting for years and should provide a valuable burst DPS cooldown that will serve the class well in both PvE and PvP. We have yet to get confirmation that this ability will be available to all hunter specs, but since Ghostcrawler referred to it as a hunter ability rather than a beast mastery ability, it seems likely to be a class baseline ability that enables every hunter spec to unleash a frenzy of rabid death into their opponents' faces.
I don't think we have talked about what we are doing for the hunter yet. I think a lot of hunter players have guessed it but the hunter level 87 ability is basically you get all your pets at once for a short amount of time. So if you have 5 pets in your stable, they all come out and do damage for a little bit of time, and that's really fun cooldown for them. I think it increases Beast Master's damage by 80% while they're out, or something ridiculous like that. That's a pretty fun one.
