Wowhead's being unhelpful on the subject. Can any beta engineers, who have made one of these, answer a few questions about the enchant? How long does the invisible effect last? Is it just crappy belt slot version of the old invisibility generator, or does it last for a decent length of time? Can you move while it's active? Can you use it right from Mage invisibilty/Hunter FD/Shadowmeld? Does this thing even still exist or was it replaced by the holographic target dummy thing.
Also, is there any sign of a new engi teleporter device besides that near worthless hearthstone replacement?
