Well as a multiboxer the thing I personally suggest for gold making is using your excess amount of characters in order to level professions and then just supply things such as living steel that have a daily cooldown. It gets better if you have say a blacksmith as well to provide belt buckles. I also still enjoy the glyph market. The nice thing about professions is they can be maxed at level 80 so you don't have to continue a team if you dont like them. Granted it will change to 85 next expansion most likely. I enjoy the living steel market so much I made 18 alchemists. It has paid for itself easily over time. This patch helped even more since with the introduction of the Sky Golem living steel is still in high demand. Just my thoughts on gold.
