So with blizzard making an obvious move towards mobile gaming I was wondering what that could look like (positively) in the case of WoW.
What I came up with is moving PvP pet battle functionality to mobile.
With this you should be able to assign your team from your phone and queue up to battle.
Personally I don't care to use my computer time on PvP pet battles but I would definitely play it as a phone game.
It could also make those pet battle PvP achievements a little less cumbersome.
