If you remember a decent portion of pathing for a classic zone, here's one thing you could do. Take a map of the zone, blow up a portion of it, mark it up, make a google doc out of it, and see if you can get enough of a concensus on the scribbles, or some archived posts to back it up.

If nilbog likes it and gives the OK, I'll try to make it match up somewhat.
