I know this question may be moot with the current xp nerf. Maybe it's a stupid question anyway.
But, I was wondering, would it be possible to bring a low level alt to Pandaria and then do pet battles? Do pet battles give you more xp the higher the level of pet you're fighting? (So fighting lvl 25 pets would give you more xp?) In which case you could speed level your alt while you level your pets.
Of course, you'd have to get your alt somewhere there are pets to battle and no mobs around to kill you....but maybe it would be worth it if you could find such a place.
Thoughts? Or is it just wishful thinking?
