Cataclysm is still new so the AH prices is still really high so i found a new way to make a pretty decent amount of gold by killing birds in Uldum with 10K HP
Here is the spot
The item your gonna farm is Delicate Wing, it has a really high drop rate as you can see here.
Now to the math, I was able to farm all this by 1hour of work
132x Delicate Wing, sells for 12G EACH on my server on the AH
216 Gold in greys
And a few greens i wont count into this, since it can be luck
That means we end up at 1800 gold for 1 hour work, thats not too bad. It's not a goldmine, but its okay.
You should be able to make at least 20-30% more if you're using a range class and dont have to fly up and pull like i did on my dk.
edit: the reason why this item is so expensive right now is cause its used for Broiled Dragon Feast (The new feast in cataclysm, until we get another one)
