Historically, World of Warcraft sales have been strong with PVP equipment sales. Most of the items are inexpensive to craft and can easily double or triple their value. At one point there was a 10x profit margin when PVP was in high demand.
Lately it's become more difficult to make sales on the open market. I still do sets of players who want to outfit a new level 90 for pvp. And I still make decent sales of PVP pants and chest gear. But the market became saturated with players undercutting the market instead of keeping it at a healthy price point. Even to the point that some players were priced below costs to recoup some of the money they had spent earlier.
As an expansion matures and more people become burnt out on content, they look for other options for in game entertainment. PVP offers that option because of the quick queues and even quicker games. With the changes of the PVP queueing system that allowed players to queue for what slot they would fill (healer or dps) it make those queues seem to go much quicker. Maximizing your conquest/honor points for the week for higher gear became a lot easier.
This will cause a problem later on because the quicker players can get into higher end PVP gear they are less apt to spend the money for the 'starter' sets. They might pick up a pair of pvp equipped pants or a chest piece, but the bracers and boots and the lesser demand items can go unsold.
So making sure that you are getting the most bang for your materials buck becomes very important. If you can sell 2 pairs of boots at a 50g profit, or a chest piece that requires the same basic materials for 500g profit it makes more sense to craft the chest piece.
Controlling your own markets and knowing what the going price on items can make your goblin life a lot happier and financially healthy.
