The other day I was in a Gnomer run and messing around killing the Gnomeregan Evacuees and noticed they spawned instantly so I sat there killing gnomes with little to no effort they drop silk and a decent amount of cash so it's definately worth not only that if you attack one the other one doesn't aggro...Great stuff I'm not sure if they give any Experience but, I'm definately gonna try it out but, I'm 100% they drop cash and silk..Hope this proves useful and have fun people.
