Drain tanking has never been a good idea
The great thing about lock is that you can kill 2 to 3 mobs at the same time as a chain with little to no downtime
You puts the right amount of dots for the best balance/threat generation on the mob your void walker tank, and you fear/dots wand another mob
When you need to recover health/mana, you focus on a single mob or use bandages while your voidwalker/dots are focusing a single mob
On Twow, afflictions didn't receive that many good buffs while leveling
While demonology received a ton
And destruction is only good if you are willing to spam a mage for both food and water and if you know what you are doing (you don't)
Focus on talents that improves your pet and its regeneration, not your own, and you should be fine
Succubus is a noob trap on classic/vanilla, but I heard she is busted on twow, so check that too
