Affliction for me. I've always had greater success leveling with Affliction as the ability to tackle multiple mobs is so easy. The DoT, DoT, DoT, Repeat on 3-4 more mobs, Howl, Life Drain, method works very nicely.

I haven't worked out how my talents will work in Wrath, but I find a 41/16/0 ish build gives you fantastic survivability with those Demo points, really high stamina, and Dark Pact never lets you down with the Demonic Intellect talent. Sure your a tad gimped on damage having little to no destro points, but that doesn't matter when your grinding out 30 mobs for a quest. The faster the better and taking 5+ mobs down at once with an almost non existent down time helps.
