I'm killing boars in Goldshire till 70

nah just quest, instace, farm .... pretty much what ever you like .. Keep in mind though some levels you won't even notice and some levels make you wanna give up.. (Had a hard time at 41, from 44 suddenly my quest logs got to small and got to 50 without really knowing it)
My point is: gogogo and go your own way :thumbsup:

Good luck!
