Hunters, warriors and rogues are all designed to eat locks.  With an equally geared hunter all you can do is dot the hunter and his pet, while hiding behind trees and rocks and stuff.  Use death coil early on the hunter to get time to put dots up and just hide as they tick him to death... hopefully.

Can't really say the same as any of you. I'm 70 lock and have tried every spec except raid spec and when I see a hunter I first check his gear fast and in case he's full venge then I run XD but otherwise I can take them. I'm playing as sl/sl but I didn't have a problem as destro either. Aff just isn't for pvp. A hunter do the fast damage so either you have soul link and can survive it so that he dies before you do or u have better nuke (destro ftw)
