You can see the original post in the Alpha forums but I dont have alpha so I cant post there.
Anyways, please dont remove pet battles, expand on them. Blizz says in the blue post: “As time has passed, we’ve seen fewer and fewer players enjoying pet battle combat, so this is an area we want to iterate on.”
As someone who loves pet battles, you know why I engage in them less? Because you have already near abandoned them. There were no wild pets in K’aresh, no trainers to fight. There hasnt been a pet battle dungeon added since BfA.
