I have been wondering this also. I've been trying to plan a build for a few weeks now, and am kinda stuck. I guess I am really worrying about it too much as I am only 43 ATM. All I have really decided on is that SM, Dark Pact, IHoT, Demonic Embrace, Imp. Imp and Shadowburn are things I feel I must have. With the leftover points, should I move the rest of the way down Affliction for , or go for more Destro(read: Ruin).
I would like to be viable in both PvP and Raids. Which is the better choice. I still have plenty of time to make these decisions, as I still need to get Shadowburn and IHoT, but I'm just lost after that.
