I like the power that a full lvl 70 affliction build can do, and the massive DPS that a well geared, even well geared pre kara affliction lock can do, but what about lvling as affliction. I know that many people have done it without to much hassle, but I am a little leary that if I spec out of demo and lose my good friend felguard that it'll be a little harder to solo some of the elite quests that i can do with felguard now.
I was thinking of doing this build if I went with affliction, essentially the cookie cutter build that many new raiders will use.

I might change it a little to put 2 points into howl of terror if I decide to do much pvp, but at this point I think I'll just stay PVE and hit the PVP stuff on hunter/rogue
