Here's the cut and paste from the 1.5 notes on Crafting (which haven't been reversed yet. I also remember them talking about some item (bag of random goodies?) that you can purchase with Artisan Marks that will be added in. Expect the popularity of Crafting rifts to go up if you can start getting plaque rewards from any crafting rift :-), although I suspect if they don't drop the cost of the Artificer one that there will be a lot less lures made if people can use the plaques from any other (cheaper) profession for Artificer recipes.
No word that I have seen anywhere on new recipes.
CRAFTING
* Skill-specific Plaques have been converted into Master Crafter's Marks.
* Master Crafter's Marks will now drop and reward wherever the previously skill-specific Plaques would (Apothecary Plaque, Outfitter Plaque, etc.).
* All Epic crafting recipes are now purchased with Master Crafter's Marks.
* Reduced the amount of Eternal Planar Dust required to make the components for the weekly Crafting Rift lure quests. Slightly increased the amount of store-bought materials needed to offset the cost reduction.
* You can now receive Inert Shards, Stones, Gems, Crystals, and Prisms from Apothecary daily quest reward bags and chests, as well as Apothecary Crafting Rifts.
* Skilled Alchemists can now obtain the recipe for Pure Valorstone from the Favor Quartermasters in Sanctum and Meridian. Pure Valorstone can be used to add Valor to crafted armor for those looking to gain a leg up in the battlefields of Telara. The crafted armor must be of level 47 or higher to be made with Pure Valorstones.
* Endurance bonuses from crafted item sets can now stack with each other.
* Fixed the skill level requirement to craft Carmintium Lariat.
