You perhaps want to read this and then find a crafter in your guild (or take some time to find a crafter in Trade Chat). The guide below says what is “best” (always comes with caveats), so if you intend to offer crafting services to others, look for gear that is in-demand on your server (since crafted gear is still server specific, which includes “connected realms” for low-pop server, but it’s not region-wide like crafted consumables such as flasks, food, & potions).
P.S. It’s late in the season to start leveling up a crafting tree, but it might still be useful to “catch up” so you are ready to go for Season-2 when demand for crafted gear will pick up again.
