I could pay for my 5 with tokens, without any farming. My main teams have herb/mining and I just collect while I am out doing other things. The combination of herbs, ore, WQs, emmisary chests (2000+ gold each), and just playing and having fun makes me about 1.25 million gold a month.

This late in the expansion the herb/ore market is low, as well as pets, BoE gear, all very low. So many have unsubbed and waiting on the next big patch or expansion then the market will pick back up. You can still make gold doing the AoE semi-standstill hyper-spawn farming. The BoE market has tanked but just the raw gold and vendor trash is good. You do not even need to multibox, just join a 2x4 group in LFG.

I prefer the fun method over the farming method.
