Hey guys!
So, I've seen some people wondering where our garrisons will be located and what will there be on their spot if our garrison is in another zone ( for example, if my garrison is in nagrand, what will take the place of the defined spot for garrisons in shadowmoon valley ). Thus I've made a comparison between screenshots from garrisons ( Shadowmoon Valley garrison preview ) and the Shadowmoon Valley and I've figured it out.
This is the map for Shadowmoon Valley, as you might know heh. Now look here. Our Garrison in Shadowmoon Valley will be placed right there. And if our garrison is somewhere else this is what the place will look like. In this screenshot you can see the lake to the west of our garrison's location and the little isle inside the lake. You can also see the hills above the lake. You can see the river and the way it maneuvers. It's the exact same river that I've circled on the map. Here you can see the Temple of Karabor in the background behind our townhall ( rank 1 in case you don't recognize it ). So yeah, when you put all these screenshots together you get the exact spot of our garrison. I hope you enjoyed reading and I hope this was helpful to more people than I expect ( as it might be too obvious for some very intelligent expert ). ^_^
Edit: Originally I thought this was the spot, but thanks to Lodovica I've realised I was wrong.
Update
When I first saw these screenshots I thought this one is the Gorgrond one because of the hill in the background ( which looks like those Grogrond volcanoes ). But after seeing the Draenor map today I noticed something. This is the Spires of Arak map. You see that alliance fortress? That's our garrison. That volcano/hill in the background is actually one of the spires of arak :P The spires of arak, as you can see on the map, are in orange ( dirt ) and black/brown. I can see the spire in the background follows the same pattern. You can see it on the fourth and fifth screenshtos from the garrison preview ( the one I linked above ) right above the jewelcrafting house. Also, as you can see on the screenshots, the zone/area looks complete and when you look at Spires of Arak map, you can see how the zone is pretty empty ( those big brown fields with nothing on them ) but that specific area ( the alliance fortress ) is complete :P
I also found this. This confirms our Garrison's location in Shadowmoon Valley. It's exactly where Lodovica said.
I am wondering where this garrison is located. None of the zones has dark blue-ish trees and skybox. In fact, only 2 zones have similiar trees. Spires of Arak and Tanaan Jungle. I think this is again Spires of Arak but during the night. Tanaan Jungle's trees are way too green ( according to the Draenor map, which is like a screenshot from above ).
We were shown this screenshot some time ago in one of the Blizzard Dev tweets. I found it on the map too - right here. There isn't even a need to point out the similarities :P
