Eh. It may have been an issue before but Garrisons made it 20 times worse. Before the "fix" in 6.2 to treasure hunter followers you could make tens and thousands of gold a day just by logging into your toons. Pure stupidity on Blizzard's end to allow that to happen and it went unchecked for more than a year so I'm sure there are plenty of casual shitlords sitting on multiple gold caps farmed almost exclusively from their Garrison.
