There are literally 3 usable mats. Why?
Because Expulsom, Hydrocore, and Blood-Stained Bone is why. These are the things you don’t need either Expulsom, bones, or Dungeon BoP mats for:
-Barding (consumable)
-Barding (mount equipment)
-Diving suit (consumable)
-Diving helm (consumable)
-converting Tempest Hide into Hardened Tempest Hide.
For everything else it is possible to make, you either need dungeon mats or you need bones. Because where does Expulsom come from? Scrapping. And what can LWers make to scrap? Leather & Mail armguards. Which require bones. And because you can use leather or scales to make armguards, but both require the same bones, Blood-Stained Bones become the only remotely important Leatherworking mat.
For Tailoring and Blacksmithing, low level gear is made with thread or flux. Both of which can be bought from a vendor. So for those professions, the Expulsom grind uses only one kind of low-level material, which makes it considerably easier to make. And because there’s no bottleneck on low level gear, there’s no bottleneck on Expulsom. And because of that, the higher-level mats for those professions are far more valuable.
Meanwhile, I have 6661 Hardened Tempest Hides that I literally cannot use unless I farm up ~30 bones per each Expulsom needed. It would take between 40-333 THOUSAND bones to use that many hardened hides. That’s at least 300k gold in bones at their current value. All of the hides, otoh, are worth 666g. Woo.
There cannot be a bottleneck like this. Blood-Stained Bones need to become a vendor mat so that LWers can make their low-level gear with the same amount of restriction as every other profession. Being gated behind bones destroys the rest of the profession mats LWers use.
Making Expulsom BoA would also go a long way to helping. It would make ALL the professions run more smoothly. These BoP mats are always more annoying than they need to be, especially when there are 4 of them! Or even add a vendor selling Expulsom. Have the mount vendor in Nazjatar sell a BoA container of 3 for 100 pearls. Given the proc rate of 1/6 to 1/8, it costs 30-40 Prismatic Pearls per Expulsom already, it just involves a lot of annoying busy work, clicking “Ok”, and RNG. I literally created a “click OK” macro just for the incessant confirmation dialogues from buying and mailing benthics.
Finally, in Shadowlands, PLEASE don’t make the BoP crafting materials required for EVERY RECIPE again! Crafting in BfA was better than WoD or Legion, getting pretty close to the Goldilocks zone between those two extremes, but Expulsom really put a damper on the whole endeavour.
