Many people say skinning is useless, but i found a way that i earn a lot of money with!
Its all about this item: Windscales Wind Scales - Items - World of Warcraft
They are needed in many of the new recipes in 2.4 and also in the BT Recipes, so i can easily sell 10 of them for around 90 gold.
They are very easy to farm in BEM in a area called "Scalewing Shelf" Coords: 67, 65. They are dropped by Felsworn Scalewings and Scalewing Serpents, the drop rate is around 20% so the drop rate isnt low at all!
Then another good thing about the Scalewings is that they drop: Serpent Flesh Serpent Flesh - Items - World of Warcraft which is used to craft the 23+ spell dmg food Crunchy Serpent: Crunchy Serpent - Items - World of Warcraft
Hope this helped some guys
