Since then a couple of things have changed such as zoning nerfs, and the steady fall of cross realm assist. I did my research, and from that I compiled a good list of working farming spots can bring in some gold.
Here's a list of farms (with a video I created) of 35 spots that still work. The video REALLY helps you nail down the specifics of each farm. I suggest you use it as a reference. If you watch it on youtube, you can see specific time stamps to the location of each spot. You can also enter the WoW gold token giveaway I'm hosting on the video. Good luck.
