Does anyone know if Blizz has mentioned at any point adding an option to the Pet Battle interface that allows you to save teams?
Personally, I like to use high level pets when I'm on my main, but while leveling, I like to use pets that are either themed to the character, or at least level appropriate for the content they are in. When switching from one toon to the another, I find that I frequently will attack a wild pet with the wrong team, or forget to reset the abilities when I swap a new pet in.
No, they haven't. In the meantime: http://www.curse.com/addons/wow/pet-battle-teams . Works wonderful, even saves the abilities you want to use and you can name the teams for easy recognizing.
