Coming back for at least a month for Cata. My main is a miner/EGR tankadin, and I am curious as to what engineering will get in this expansion. I have read about the cogwheels/hydrolics, and while they look cool, it doesn't seem like I can use them in any helm that isn't an engineering craftable, and sadly there is no tanking head piece from what I have seen.
Do we get any new toys or portals? And is there any other good tinker besides the shield for tanks?
