Im a little leecher as MMOWNED.COM says.. So I'll contribute.
Im going to tell you how to make alot of gold using a very fast method that can be used by both factions.
Alliance;
Once level 15, head over to Darkshore(Night elf 10-20 area) and walk northeast until you see Moonkins.
Farm them, they will drop Light Feathers(Light Feather - Items - World of Warcraft)
A stack of '20' sells from about 5gold to 23gold depending on the server type.
I farm these daily if I need a restock on my gold, I usually make about 200G a day using this method.
The reason people need Light feathers is mainly because two things "Priests and Mages". Spells used for are 'Levitate' 'Slow Fall' and 'Floating'. To be more specific they drop off;
Moonkin
Moonkin Oracle
Young Moonkin
Raging Moonkin
The coords are 43.6,46.0
Horde;
Now since I'm mainly an Alliance guy, I don't play to much Horde, but I know some stuff about the area.
Head over to Crossroads(11-20 Orc/Troll area)
If you can pick up some quests that tell you to go kill some harpies.
If you can't thats perfectly fine. But, the Light feathers drop off the Harpies.
Both factions drop rates are very high, and a x20 stack can be aqcuired within 30 minutes.
So, go kill harpies then again go AH them for some gold. They also drop from several plainstriders. For those who are level 12-14. To be specific, the harpies names are;
Witchwing Ambusher
Witchwing Harpy
Witchwing Slayer
Witchwing Roguefeather
Witchwing Windcaller
The coords are 41.5,15.1
Hope you gain gold!!:wave:
