Here's another terrain exploit I found today while exploring around in WSG. Like my last one, this one is also very useful for hiding the flag. I think many of you will recognize this area from countless WSG games, but with a little walljumping it is much improved indeed.

All you gotta do to get down from this one is just to hop back down the way you came or optionally drop down the left side there, though I'm not sure how much fall damage that would inflict on you.
Happy exploiting!
