A few LLLLP questions

1- Without a tank, it is required and it doesnt work even close to as well as mages. Void sacrifice helps. Just stick to lower level mobs, warlocks lack the talents that mages get. Warlocks have higher damage and no threat reduction while having no talented spell hit outside of affliction. That kills our destro dps against anything other than mobs our level or below. So like mentioned, stick to lower level mob grinding and just pull larger pulls.

RoF is one of the lowest damage aoe's. Hellfire is the highest aoe damage.

2- Without a tank i think it's the best option. Even slow dots will pull aggro from voidwalkers well before the mobs die. SL drain tanking is the best option with no dedicated tank. 31 demo is very costly in the single target damage department. You dont need single target raid damage for dungeon bosses so it can work and it's great for pvp.

3- you can spam holy nova for aoe pulls. You'll be out of mana after about 7-8 casts which is about every pull. Prayer of healing works very well, it's far better in any situation where you can cast.
