So if I understand correctly, Blizzard are reworking Hunter pets so that none of their special abilities are damage-dealing. Which means that Spirit Beasts will lose their Druid-like [Spirit Strike] and gain, instead, a healing ability.
I didn't come here to QQ, but I can't help but be disappointed. I'm sure that raiders and people who party/dungeon a great deal will enjoy the changes to pets, however. Every pet is getting some sort of "species-specific" buff/debuff, meaning that now Hunters won't be "required" to bring a wolf to every single event.
