Farming as in... grinding mobs? Well, as far as we know that'll work as well as ever.
Farming as in... your MoP farm? Nope, but you can still go back and use that one.
Like Tillers? Not sure yet. I know they were including Fishing Shack, Mine, and Farm for the Garrison. But I havent seen it on the blueprint list. Might be something you unlock via questing. But I am not sure it will be the same Tillers where it will provide all of the materials youll need for different professions.
