We’re not going to blow anyone’s mind by stating that pets are pretty central to the experience of playing a Hunter in World of Warcraft. You can eschew one altogether as Marksmanship, but they’re still pretty darn important. The developers have put together a long post discussing the mechanical changes coming to hunter pets with the Battle for Azeroth expansion. No, you won’t be able to choose your pet’s specialization any longer, but that’s because all three specializations are now meant to simultaneously tank while solo and provide DPS through other means, while pet-specific abilities are becoming more varied and potent across the board.
But there’s plenty to discuss even outside of official announcements as datamining has uncovered what appears to be broadcast text for the siege of Lordaeron and the attack on Teldrassil (i.e., the events that kick off the expansion as a whole). There are also new bits of datamining suggesting that First Aid may be rolled into the Tailoring profession, as well as a new mount that strengthens the hints of a mag’har allied race for the Horde. All unannounced thus far, of course, but still exciting fuel for speculation.
