Unless I am mistaken, I believe this is referring to the pet battle PVP opportunities. I would love to see an option like follower dungeons for pet battles where you can actually battle NPCs and their team the same way we do with the current pet battle trainers. It would essentially be a solo queue where you would select your team ahead of time and then the same way you would initiate battle looking for another human in this case, you would simply look for a computer match.
