So I found this exploit together with a friend of mine and I tought I'd share it.
Everyone knows the exploit to get on top of the Stables building, but here is a twist.
As a Gnome you are able to get inside the building on the top.
From there you are able to shoot trough the windows at Horde that are trying to cap Stables without them being able (atleast at first) to find you.
