Are the orc's in Nagrand the best place to farm netherweave? What is your opinion's and suggestions?

According to the search on here, Skettis looks to be one of the best places; the Skettis Sentinel has a 56% chance to drop Netherweave. I personally always get a couple of stacks just cutting through mobs for my SSO dailies. I'd go with either Skettis (keeping an eye open for herbs and Ancients) or Blood Elves (Netherstorm or Quel'Danas, your choice). Not sure if they're the best, but they're steady.

Or, you know, farm something that makes more, like primals, and buy the netherweave off the AH. That works well too.

If you slaughter the Sunfury bloodelves in Netherstorm, you should end up with a lot of Scryer rep items as well (Armory shows you only at Revered). This'll go even faster (and net you some gold) if you manage to work in the Scryer quest chains that start in Area 52.

Try the Ogres in Nargard.
they drop alot of coin, cloth, and other items of value.
Each kill gets you 10 rep for Kularnia (spelling?) if your alliance, or the horde equilivent.
In addition to 10 rep per kill, they drop the beads that you can then turn in for further rep with the consortium or Kularnia.
you'll farm your cloth, and get rep per kill + turn ins for more rep with 2 option of 2 differnet factions. sounds like its full of win to farm the orges
good luck

As a tailor, I need more netherweave than I get on my own in order to level/cap. After all, 3 stacks of netherweave=10 bolts of netherweave. Thats enough for two low-mid 300 level items.

It also makes just over 3 bolts of imbued netherweave (3 per). You need those to cap tailoring. The imbued pants takes 4 bolts and the robes needs 5.

So while we do get a lot of netherweave, it's not nearly enough to level quickly. I saw somewhere that we'll need around 2200 pieces to cap tailoring? At 3 stacks a day, that's still 36+ days of grinding.

Now, with that all being said, I still don't know how productive intentionally farming netherweave is. As mentioned above, doing quests that involve killing humanoids will generate a steady stream, and you'll get the extra rep/xp/quest rewards as well.

I'd also ask your guildies/friends for help. The non-tailor ones are generating far more cloth than they'll ever need for bandages. Let them know that if they get you the mats (plus a stack or two extra), you'll gladly make them the imbued bags. This is best while you're getting skill ups for the bags, but still works afterwards. The extra netherweave they'll give you can be used for higher level stuff. Plus your guildies will remember to send you their cloth, even after they're all bagged out.
