Here's a spreadsheet of all the new crafting recipes for those of you who wish to dive into an expertise since all but end game gear is no longer NPC-craftable. Even if you don't, take a look anyway and don't incinerate these mats.
I suggest hoarding materials until a double proficiency event takes place.
What you should craft will vary depending on what you pick up and Marketplace prices and supply.
Dismantling and Element Stone crafting is unlocked at 100 proficiency by speaking to respective NPCs.
On another note, if you have Cooking skill and Element Stone, the lack of space on the Talent menu may result in the inability to view your crafting recipes away from the stall because the tab will not be displayed.
Here are farming location recommendations for those looking for some. Use low level gear or take only your weapon to lessen repair costs.
