i.e. If you can only craft iron for blacksmith well.... i don't think you'll get anything above iron. Regardless of lvl.
I'm v8 and getting v16 mats because my smiting is maxed (9/9 for quality crafting)
My only alt is 3/9 for enchanting potency and I can used over half a dozen potency runes (I never receive runes I can't actually craft with)
See i'm not sure cause I've got 50 in one craft line and I get ok stuff but I have all points in another and get much better stuff both are 50 and 50 but one has all skills and the other has only hirling 3/3
I guess I'm wondering if I need 3/3 metal extraction and 10/10 metal working on a level 50 blacksmith with 3/3 hireling vs level 50 with 3/3 hireling ?
