Yes, but the best missions are ALWAYS available. I'd kill for a yellow underworld metals mission every time the previous one ended.
I feel your pain, because I would love that too. But I accept the fact that UT missions are random and I therefore take the best I can get. Usually that means one or two non-gift missions. Whether fabrics or metals, I have the characters (and companions) that need both, but at the moment I have no immediate need. So I do what's available: I look for bountiful and rich missions at lower levels and abundant at grade 6 . And I continue to stockpile materials for the day I do need something.
