I play a 7-4-50 lock, and manage to own most hunters just out of pure damage output. The trick to the build is the clear-cast proc, which can really eat almost anything save for rogues alive.

The other bonus to the build is the lack of lengthy damage-over-time. I know thats where alot of the fun to the warlock comes in, but nuke-for-nuke I can match if not outdamage a hunter pretty easily.

The extra stamina seriously comes in handy, as well!!
