I don’t usually do a lot of stockpiling between expansions, even though I know a lot of other goblins do. The biggest thing these days seems to be getting ready for relics in Shadowlands, but with no updates as to when pre-patch is hitting, I’m not even sure that relics will make it in as we know them right now.
They work simple enough. Craft an item, apply a relic to said item, and something changes. When you add relic V to an item the vendor price goes up to its maximum value. It takes time to craft the items, time to craft the relics, time to sell. gold per hour is calculated on all of that.
Right now the most popular crafted goods and relics seem to be linen and copper. I’m stockpiling a little of everything that I find for cheap, but I’m really not going out of my way. The rest is just stuff I’ve had in my banks forever that might actually get some use. I’m not stockpiling sky golems either because I think there will be a huge influx of those as people realize how quickly alts can pick up the recipe and begin their sky golem army. I predict the price will drop. I do have a few in reserve, but no huge amounts. I would rather make my gold from Shadowlands items, but still branch out a bit into the older markets too. We’ll just have to see.
