Did you hear that the next patch is supposed to be the battle pets pass? Well it is according to muffinus on twitter. Muffinus. I’m sorry I killed the muffin thief twice. We’ll have a link in the show notes, but the gist of it is a new currency which we’ve talked a tiny bit about, some new spells, and a few ability changes (https://us.battle.net/forums/en/wow/topic/20762158027). They are also scaling the pet levels of TAMER pets. Tamers will also scale to the highest level pet on your team.
In addition to the update post, Muffinus also wrote one about the philosophy of pet battles. It discusses the idea of them retiring pets (see also, nerfing), to give other pets time to shine in the next expansion. This allows collectors with the largest collection to essentially cycle through to find other rare gems. (https://us.battle.net/forums/en/wow/topic/20762158027?page=2#post-24)
