Normally, when Blizzard makes a change to the economy, it's not enough news to justify its own blue post. When I sat down and tried to decide what to write about this week, I realized that the most important information I could get out to you guys is news of all the economic tweaks that have come down the pipeline that are shaping these first few weeks of Cataclysm.
First up: Pyrite Ore is now prospectable at 500 skill, down from 525. This is a very expensive mineral on most realms, so it hasn't been prospected as much as, say, Elementium Ore. That said, based on the limited number of prospects we've seen numbers for, it looks like it may be dropping as many green-quality gems as Obsidium Ore, as many rare gems as Elementium Ore, and an additional one to three Volatile Earths. My napkin math indicated that if the additional expense for five pyrite is more than two earths, it may not be worth prospecting.
