So these are the four dungeons that come to mind having a 3D space in which we must move. The 1st two are disliked by many folks, personally I love the pit quest but alas the 3D spaces are mapped in only 2D thus navigation is made more difficult.
We must traverse up and down, N/S/E/W, and backtrack across multiple levels in these dungeons as we progress towards completion.
Might it be possible to give us a 3D mapping function of these dungeons?
Here is a wonderful example of a static map of The Pit that could form the basis of giving us an improved dynamic map that actually helps in navigating the quest. By dynamic I mean it shows the blue party member dots tracking through a 3D map as opposed to the 2D representations we presently have for these dungeons.

Thanks to the individual or group that made this map!
