I wasnt sure where i shouldve posted this but i hope it fits in here.
I discovered this by accident, I used my Faded Wizard Hat (Faded Wizard Hat - Item - World of Warcraft) and got goblin female, I'm just using it every 30mins cd too see what i will get. I was kinda dissapointed since ive got that like 5 times in a row so I used my Darkspear Pride (the thing that transforms you to a darkspear troll, http://www.wowhead.com/item=54653) and I became a FEMALE troll. Maybe it's been posted before, i don't know, but it was still kinda fun since model edit's doesn't work atm and stuff.
