My wife plays Enh spec. She was able to get various weapons, all ilvl 450 and below, from the AH, that were world-drops. There are no crafted weapons for her class/spec. This means she has to look elsewhere to increase her ilvl, and she has no more options than I do for available items in all other slots. She was eventually able to replace her weapons after running a large number of scenarios.
From what I can see, crafted weapons at ilvl 463 or higher are available for every class and spec except for Enh shamans and Combat rogues. There are AGI daggers, but the speed on the weapon is 1.80, far too fast for Enh, and I think Combat also uses slow-slow.
So did a blacksmithing pattern get left out somehow?
edit: apparently the crafted shield comes up as "Darkmoon Murloc", which is funny....
