wow.. where exactly is this?
surprised The post before yours explained it pretty well. When they released ZG, they did some mega changes to the instance (as can be seen by anyone who is ever bored enough to climb to uninstanced ZG). When they set up the actual instance, they left in the alpha versions of two zones, Deadwind Pass and the Blasted Lands.
Pretty much for anyone experienced in wall-jumping, this should be cake.
