Update 8/22: This article is still mostly accurate but is slightly depreciated. It will give you a good overview of the overall changes but you may want to view more recent posts under the Beast Mastery tag for more info and recent opinions.
If you missed it earlier, Blizzard released the first version of patch notes for the Warlords of Draenor alpha. I’ve summed up all the relevant hunter info in this post if you want to catch up. I’ve already taken a closer look at both survival and marksmanship, but today we’re focusing on beast mastery.
Overall, beast mastery looks like it’s going to see the least amount of changes in Warlords. Blizzard’s goal with the hunter changes was not to revamp the class, but to give each spec a better identity. Beast mastery already had its own identity as the pet-focused spec, but it looks like Blizzard is aiming to reinforce that even further.
