I want to transport to area 52 since I started engineering.But when I am at level 70 get gnomlish engineering 369piont, I found only goblish engineer can transport to area 52.I try to use Soothsaying book in Steamwheedle Port (in Tanaris) but it doesn't work,I'm confused whether I can switch my engineering to goblish on Medivh sever?
If i can,how to?

Thanks alot!
