This was the topic this month followed by my answer.
Using your knowledge that you have gained from auction house experience: If you were starting over as a gold maker, what is one thing you would do differently than the first time, and why?
Don’t stop farming, so you can build up capital faster.
Going from 1k to 100k is normally the hardest phase in gold making. This is because you don’t have the money to power level professions. You are limited in how much you can invest in ore/herbs and you generally tend to be very risk averse.
For me when I started out back in vanilla I farmed herbs on a prot warrior but once I started making money with buying herbs off the AH and making potions/flasks etc. I really cut back on my farming.
If I had continued to do a little bit of gathering before and after raids I would have made more gold so I could buy more things to craft with. By the time AQ20/40 came out I had enough gold I could start doing some market manipulation with living essences and large brilliant shards. If I had continued to do a little farming on the side I would have had more funds to make even more gold.
I learnt my lesson and even now sitting at over 1.5 million gold I still do some farming from time to time. From rare spawn farming to gathering amazing amounts of herbs on my Tauren Druid in 1-60 zones it’s all good.
