Proffesions aren't considdered to be a goldmine in WoD.
They will all be able to make some, but not the way we used too.

I'm rather sure they are trying to bring back farming
With BoE drops and other drop materials, especially sinse
the "potion of luck" farming became such a big thing in MoP.

They have also said that justice and valor are going away.
There will be rep and gold venders insted.

So I believe they are trying to make gold a big thing again.
