while i dont lpay my mage much in pve now as after clearing icc im totally bored. im looking towards the future. and fire mage will have some fun. i intend to go fire for catc and many of as are thinking the same(for pve). the new reforging vender will let you half any stat(not stam or int) for another stat that doesnt already exist on the item.
as a fire mage i will most likely be halfing haste for crit, if it isnt there, or more likely mastery as it is so imba. wht you think, link below is TotalHalibut video on reforging:
