Basically asking for a history lesson here, I never invested that much time into WoD and I often see comments of people saying they hit gold cap multiple times in WoD, with even some of my more casual friends saying they made enough that expansion to last forever and that it had a significant impact on the overall economy of WoW. Is this hyperbole or exaggerations? Was it actually that easy and what were the methods?
Please educate me, I love learning about quirky things in WoW's history.
