I am still working on several promised posts, however I can dash this one off with a minimum of time investment, so naturally, these types of posts float to the top of my priority queue ;)
ps. if you only like my writing on hunter PvE and don’t want to read my rare economic posts, just skip this one.
3.2′s largest economic change is going to be epic gems. They will be prospected from titanium ore, and since this gives blacksmiths (who get additional gem slots), all other professions have been given slight PvE buffs to make up for it. On my server, the price for titanium and it’s derived products (titanium bars, titansteel bars, choppers, BoE craftable epics, etc) have skyrocketed due to speculation.
Conversely, the demand for saronite, while holding fairly steady for now, can be expected to drop since most people won’t be using the gems produced by prospecting saronite ore (unless Blizzard comes up with some sort of sink for them). This will have an effect on many markets, including enchanting mats. Right now, the cheapest (if longest) way to get enchanting mats is to buy and prospect saronite, sell the valuable blue gems, and use the rest to craft dinky level 70 greens for disenchanting. These dinky greens also take crystalized earth, which is why eternal earth costs so much now.
The only way to get titanium is to mine high level areas, but the nodes are so rare that generally a miner will get mostly saronite.
Once the demand for saronite drops, the price for enchanting mats might go up. Despite the fact that saronite ore is cheaper, the blue gems that are currently sold for decent amounts of money will not be sold for nearly as much, meaning that the enchanting mats produced will have to carry a higher portion of the cost.
Of course, if saronite got ridiculously cheap, this situation would regulate itself. However, there’s a hard limit on the lower price of saronite. Anything less than 10g a stack and you can vendor the bars for a profit.
