BlizzCon 2016 started today!
So far the only pet news comes in the form of a new charity pet, Mischief!
Starting December 1, 100% of the fel kitten proceeds will be donated to the Make A Wish Foundation.
I'll update this post with any other pet news as I come by it.
Update 1: The Brawler's Guild will be making a return in Patch 7.1.5 (coming Soon™), which means the Clock'em battle pet will be available once again.
Update 2: PET. BATTLE. DUNGEONS. (future patch, no additional details YET) *excited*
