Grave Moss

What is Grave Moss used for and where can you find it?

First off, why should you care about Grave Moss?
I don't know. You're here aren't you?

Gathered from:
-[object=1628] which is found in Duskwood (36), Razorfen Downs (9), Arathi Highlands (7), Wetlands (7), and Hillsbrad Foothills (3)
-Only found in graveyard-like places

Where in these zones?:
-Duskwood: At Raven Hill in the northwest and Tranquil Gardens Cemetery in the southeast
-Razorfen Downs: A couple different places in the dungeon
-Arathi Highlands: Northeast part of Stromgarde Keep
-Wetlands: Just south of Dun Modr at Ironbeard's Tomb
-Hillsbrad Foothills: Only 3 nodes right in the middle of Ruins of Alterac

Which zone is the best?:
-I have not tried all of them, but Raven Hill is working out pretty well for me. Usually no more than 2-4 nodes up at one time. The only problem is that the respawn time is pretty long so you usually will have to wait for ~5 minutes (I timed it. It is usually 5 minutes, but it can be as low as 3 or as high as 8) for new nodes to spawn. If you really wanted to, you can fly over to Tranquil Gardens Cemetery, but there is never more than 1 node up at a time there, and the nodes have about the same respawn time as Raven Hill. Not to mention you would be flying across Duskwood for only 1 node. I have been able to get around 60 Grave Moss in one day only gathering at Raven Hill. I have found that the best way to farm it is to farm all of the nodes at Raven Hill, go do something else for a bit, and then come back and some nodes should be back up.

So, what is it used for?

Milling:
-Golden Pigment (99%)
-Burnt Pigment (25%)

Reagent for:
-Shadow Oil (Alchemy 165; requires 2 Grave Moss and 1 Crystal Vial)
-Shadow Oil is a reagent for [item=7374] (Leatherworking 175), [item=4256] (Leatherworking 175), Shadow Crescent Axe (Blacksmithing 200), [item=4323] (Tailoring 170), [item=20833] (Jewelcrafting 125), and Greater Shadow Protection Potion (Alchemy 290)
-Shadow Protection Potion (Alchemy 135; requires 1 Grave Moss, 1Kingsblood, and 1Crystal Vial)
-Shadow Protection Potion is a reagent for [item=7047] (Tailoring 145)

What else?
-It looks cool, being a creepy themed herb (is it an herb?) with skulls and whatnot
-You will have almost no competition if you try to sell it on the Auction House (I have no clue who would buy it though)
-EDIT: Surprisingly when I tried to sell it on the Auction House it sold very well. As I said above, there was very little competition and I sold around 100x Grave Moss in just a couple of days. It just sucks to farm it though :(
-EDIT #2: Thanks for all of the upvotes! :)

Thanks for reading! Please upvote! :)

Farming for these for Loatheb has made me want to kill myself.

But, if you are looking to farm them, I've found the best place to be in Scarlet Monastery. I'm getting about 3 grave moss and some kingsblood and fadeleaf every time i reset the graveyard.

The skill required to gather Grave Moss has changed from 120 to 105.
