I cheated and put in a priest with my locks. I went demo and never looked back. 3 felguards and a felpup rockzors/boxors. Before felguards, I used 1 void or 2 depending on difficulity. I never had any problems with aggro or healing. I love the amped up healing and 30% damage reduction in demo. Now, I admit, I got hammerd in BGs since it was back in the twink days. I couldn't get super twinks off me enough. I did fine in the open field where I could throw my pets as demon-grenades, but in close quarters, I got munched due to only fear as defense and cloth armor.

I still love them and wished so hard everyone hadn't told me not to do them way back when I started boxing, since "You won't be able to do heroics, so don't do them". I guess I can get laughed at now, but I have never, not once done a heroic and am fine with it.
