Currently the engineering profession has goggles, which use cog-wheels and the goggles themselves are currently the only items which have said socket. Based on wrath, when or wow the engineers only saw the goggles once at the very beginning of the expansion, my fellow engineers and I have been wondering, are their any plans to bring the goggles back in the Firelands, if by rep, quest or raid? and if not, will their be any way for engineers to add a cog-wheel socket to existing items, much like a blacksmith?
