At the end of Wrath, I discovered the wonders of Inscription. Back then it was an unlimited gold mine. I went from having a few thousand gold in my pocket to 100,000+ over the last couple of months of Wrath.
Once Cataclysm’s changes crushed the glyph market, I backed off my gold-making business. I still make and sell glyphs, but only enough to break even with my expenses. It has allowed me to buy some BoE epics and crafted gear, and gear up alts quickly, but I was no longer pushing to stockpile gold.
A couple of months ago I leveled a dwarf rogue to 85 for the Stay Classy guild achievement. I made him an alchemist and jewelcrafter since I had never played a character with either of those professions. Suddenly, I discovered another gold mine. Transmuting gems with alchemy and then cutting and selling them through JC, the gold started to roll in again. I can happily sit in Stormwind and watch my gems sell almost as fast as I post them, with me restocking my auctions as they go. The only limit on my profits is the amount of ore I can prospect, and the rate I can buy new cuts.
Maybe its just because of the gear influx after Patch 4.2. Perhaps this gold rush won’t keep up. I only started doing JC dailies a few weeks ago, but I’ve made nearly 50k from jewelcrafting. It has replaced glyphs as my gold making industry. (I still make glyphs, but they account for only about 1/5 of my gold income).
Why make gold? One – it gives me something to do other than Molten Front dailies when I’m not raiding. Two – my wife just started playing again and she discovered the existence of the Vial of the Sands. She’s set her sights on that, and that means she’ll be asking me for about 29k to buy the mats. My original goal was just to make the gold she needed for that, but its coming in so easily now that I’m hooked. I’m not going for the gold cap – just having fun.
