I’m writing this post fairly early. The information isn’t all here yet, but we will look at what we do know, and speculate based on the previous BfA patches to get to a better idea about what we need to do.
New content means more players
8.2 will ad new content in the form of a raid, several new zones and a new dungeon. Obviously we also get a new set of quests to continue the war campaign as well. The raid will obviously lead to an increase in demand for consumables. There is obviously room for prices to fall between now and then though, and it is always uncertain whether we get a price bump. The raid won’t open until some weeks after the patch either, so I would hold off on stocking flasks for a while.
Pathfinder part 2 and flying will be available in 8.2. This is by far the most significant change. This will make farming for materials faster than it is currently and will thus likely increase supply. I suggest checking out your realm on the undermine journal to see how Legion flying affected material prices on your realm. Either way you may want to avoid stocking up too much on materials like herbs and ores. Cloth and leather is less impacted by travel time as these are generally stationary farms.
The various buff items will be turned into mount equipment slots that can get you the same buffs. Replacing your equipment will destroy it so the value here will depend on whether swapping is worth it or if something is always going to be best (like water-walking). Either way stocking up on materials required for the mount equipment crafts can be worth it. This will also diminish the value of the Sky Golem as it does not have an equipment slot, but we don’t know if there is an equipment that replaces that effect.
We get a ton of new crafts in 8.2. The most important ones are new potions and flasks, new Notorious combatant armor, new weapon enchants, new gems and new inscription trinkets. All of these will replace the old variants as they are significantly better than the old ones.
The new flasks will require the new Zinanthid herb from Nazjatar alongside Anchor weed and various BfA herbs. They will require less of the regular herbs, but the same amount of Anchor weed. This will likely lead to decreases in the herb prices as the volume needed decreases. This is the same for the new potions that also require Zinanthid and much fewer of the current BfA herbs, so I think herb prices will be going down significantly.
The new Notorious combatant gear will require the new Osmenite Ore and Storm Silver ore as well as the familiar Expulsom. The major change is of course no Platinum ore which will contribute to the value of Platinum decreasing. Crafting up Expulsom ahead of time as well as farming marks of honor to get the higher rank recipes on patch day is where you can generate value here.
Enchanting will get both new weapon enchants and ring enchants. The new ring enchants are both better and cheaper and will be displacing the current ones, so do not stock up on enchants. With the decreased cost as well we can expect material prices to go down. Stocking up some materials is still likely optimal to be able to craft a lot of new enchants on day 1 though, as the AH may temporarily run dry. The new weapon enchants on the other hand require more Veiled crystals than the current ones. Veiled Crystals are likely the bottle neck on patch day, but it will pass and return to a similar or lower equilibrium.
Inscription gets a new set of tokens. The crafting cost is the new maroon ink, which is likely obtained from Zinanthid as well as expulsom and some of the old BfA inks. The crafting costs look like a placeholder. The trinkets are item level 400 and are likely to be highly in demand. Until we know more it’s hard to say what sort of preparation makes sense here.
Jewelcrafters get a new ore to prospect and a full set of new gems. With the new gems being better than the current crop I expect the value of platinum ore to go disappear completely. It’s no longer used for blacksmithing either, so you want to get out of that. Your gems will likely be quite worthless as well. It looks like the new ore will be mass prospectable so time to get ready for some AFK crafting. The new gems will include a Leviathan’s eye that replaces Kraken’s eyes as well so none of them will keep value.
Leatherworkers get a new set of Notorious combatant pieces. The leather pieces will use the new Dredged Leather, Tempest Hides and Blood-stained bones. The tempest hides volumes are still low, so don’t expect the price to increase. Expulsom and Marks of honor will be the way to prepare. The Mail pieces will use the new Cragscale, Mistscale and Blood-stained Bones. This means that Calcified bones are now completely worthless, maybe they get removed as they literally do not serve a purpose anymore.
Tailors also get Notorious combatant gear. They require the new Cloth material, Gilded Seawave, and deep sea satin alongside the Expulsom. The volume for Deep Sea Satin is once again fairly low so expect the price to go down here as well. Preparations are mostly going to be expulsom and marks of honor, but keeping a small stockpile of deep sea satin will ensure you can craft throughout the first week as the AH may run temporarily dry.
Materials that could increase in value
There aren’t that many as most of the new crafts will be heavily limited by the new materials. The only old material that could see an increase in demand is Tidespray Linen as Expulsom crafting takes off for all the new items. I don’t think it will increase much though as it is already very abundant and easy to farm.
My best tips is to stock up on expulsom and marks of honor if you have an armor profession. The Sinister combatant gear was amazing for the first weeks of 8.1 and history will likely repeat. You should also stock up a little bit on the old BFA material needed to ensure you can craft throughout the first week. 1-3000 should be enough, but it depends a little bit on the market.
