Guild Wars 2

At least for Armorsmithing, these guides seem out of date.
For example, Armorsmithing master insignias require Jute/Wool/etc patches, which also require leather and the leather isn’t on the buy list on anything I’ve found.
Just trying to level my crafting as efficiently as possible.

Try gw2bltc.com and search for the item you’re trying to craft.

http://gw2crafts.net/ has guides that have up to date recipes (and up to date prices for things)
