This is my first attempt to contribute at this website. I have been here way to long without doing anything, so here it goes
First what you do is jump ontop of the little stack thing that goes up and down, like so
Then you jump to the window seal.
After that jump ontop of the blacksmith
Walk along the side until you make it to the roof.
And BAM! your there, ontop of the blacksmith, do what ever you please with this, show off to your friends, gank if your horde or just /dance and have some fun
(yes i have seen the other post on how to get up here, but this is another way )
