Mats Speculation for Cataclysm

[Ualaa]

I figure ore is useful for Blacksmiths, Engineers, Jewelcrafters and for Miners to smelt.
It its raw form, it appeals to more classes.

You have this completely backwards -

For low level JCs, you really want bars (Copper, Bronze, Thorium and particularly Mithril). Ore won't be used until Thorium to prospect and nearly all the low level gems you need in large quantities are already plentiful on the AH.
Engineers don't use ore at all, they use bars.
Blacksmiths don't use ore at all, again they use bars.
In it's raw form, it's the material for two actions - smelting and prospecting.

So you'll be selling to miners and the occasional JC who wants to prospect for Citrine or Shadowgem.
