I mean, fuck, do you see the price they want just to change a garrison ability in a zone? I don't know what's with Blizzard's gold sink obsession when they add more gold sinks but never add gold opportunities.
I'm steadily gaining money. Not speedily, but it's working out at something like 500G/day. Not quite sure exactly where from, but I tend to do a full-group heroic (So ~=75G from Stacking the Deck) and any gold-reward missions that appear each day (Well, I just do any *missions* that appear each day; go for the short-duration ones while I'm online, and finish up with long-duration ones overnight)
