Hey everybody,
I wasn't really sure to put this in exploits or exploration but as it has its biggest use for exploring I putted in here
Today I was fooling around hiding eggs (Noblegarden Egg - Item - World of Warcraft) and noticed that wherever I could "stand" I could hide an egg. This could be used to detect/discover hidden paths up mountainsides and lessen the trail and error to find good spots.
I tested this theory in the SW AH (we all know how to get on top there but its a prime example and took a screenshot to demonstrate what I mean exactly)
You don't actually have to place the egg (luckily as it has a 1h cooldown), it will show the egg icon anywhere you could physically stand and show a red icon if you can't.
This "might" work with other placement items as well such as picnic baskets etc but I am not able to verify that one...
