I believe a few of you here have had unbelievable luck, because I recently went to duo Nimbus Hippos to get a little XP for my WHM while skilling up divine and trying to farm a feather for the Bison footgear, and we didnt get a drop til our third trip there. Each trip was a 3-6 hour session each, killing 30+ hippos each time.
The drop rate seems incredibly low on Garuda, and what's interesting, is it only sells for 110k in AH. I would have just bought one in the Auction House, but they are very rarely ever on sale.
