Hi.
I hope this will not turn to be repost, but I have found it by myself.
(also this is my first thread here)
I'm hunter so I'll describe it from my POV.
Go to Shadowmoon Valley (71,34) and land on that tower in the corner.
Around that tower flies mob. this mob will not attack you/defend himself, as well as he will not die.
this makes him perfect training dummy.
Great for gathering statistics/rates/procs/ whatever ya like.
Also, great for skilling your weapon skills. ( just leave autoshot on him, place yourself in good position = easy to determine).
Name more uses of this place.
Cheers.
