Hey, a question. My guild is just moving towards HC progression and we'll be starting on Halfus. They asked me to go Demonology. I want to know, aside of obvious whelp-massacre, what can Demo lock bring there to do well? Any useful tricks? I always went Destro with Halfus-BoH awesomeness. I'm clueless about how to efficiently use demo. Only used it looong ago on Magmaw and Maloriak.
Thanks
