For too long we've been teleported to random instances with random people with no sense of a world. We could hand-wave it all away and say that a wizard did it. Well screw that wizard, I want something more concrete. Specifically I want more faulty engineering devices.
For once this isn't me asking for another awesome engineering device, though I did have one in mind: Unique and Beautiful Flower. That's for another day. Instead I want gnome and goblin engineers to devise a system of Person Subspace Somewhere Near There Transporter Devices and Day Spas. These would replace the current wizard-based teleportation for instances. Instead of being teleported directly into instances, we'd instead be teleported to somewhere very near the instance. No one knows quite where, but it would certainly be near. Could be 50 yards away or 50 yards above. Maybe you'll be in the middle of a whole lot of angry enemies. But don't worry! Most of the time you'll be in a temporary immunity bubble. Or frozen in place. Possibly also phased out of the world. Temporarily.
What's the point?
The point is to still reduce travel time so people aren't scared away from instances and to not totally disrupt questing either, since I know it can be hard to pry someone away from just needing one more drop and they'll be on their way in a minute. But at the same time, to bring back the sense that instances are somewhere.
To prevent this being used as a travel method, movement away from the instance would not be possible beyond 100 yards or so. This is due to the uh, residual magnetic defluxualization.
Who needs wizard hand-waving when we can have less reliable engineer hand-waving?
