Start with liquid gold
Separate character gold from reagents, finished items and active listings. The market value of inventory is not cash available to fund the next cycle now.
Set a protected balance for materials, fees, relisting and demand error. A discovery batch that consumes this balance is too large for the validation stage.
A discovery batch should answer one question
Choose one item or narrow category and state what the batch tests: break-even, sale speed or sensitivity to volume. Small volume is useful because it creates a cleaner signal with limited downside.
Record materials, output, list price and the Auction House cut before crafting. Add realized sell-through and the unsold balance after the cycle. Expected margin then becomes observable performance.
The current patch changes inputs, not the law of demand
Curse of Ula’tek includes a Profession Knowledge reset, while Blizzard also reduced the cost of most crafted Housing decor. Old specialization routes and cost assumptions need a fresh check.
Cheaper output can attract more sellers and compress price. Persistent Auction House filters lower operating work without creating profit by themselves. The August 17 hotfixes do not establish one universal market formula for your region.
Scale confirmed turnover only
Increase the next batch when the first sells inside the chosen interval without an excessive markdown. Stop producing when stock grows faster than realized sales even if modeled unit margin remains positive.
Set maximum inventory value, target sale time and a stop condition for a repeatable plan. The profession then becomes a managed cash cycle instead of a warehouse with no known exit date.
