My strategy leveling to 80 was similar, deep afflic including dark pact where my imp was only a mana battery. Shadowbolt, dotdotdot, fear/drain. Whenever I could, I would fear the mob before it got to me and just pulled another. By the time the feared mob would get to me, the dots would kill it and I would loot and move on. Tanking with your blueberry might be safe and all, but it was just too BORING. Using a spell almost every global cooldown, dotting and fearing as you go, constantly running around, never needing a mana break, reaping in the exp and kills? That's my definition of a warlock ;-)

/second that, Eyhk. Leveling like that also makes you much more pro by the time you hit 80.

I'm also glad to see a warlock guide that explains Drain Tanking, the quintessential warlock strategy. Drain Tanking is especially useful while leveling on PvP realms. If a ganker shows up while you're killing a mob, you have multiple ways to control the situation: Seduction, Fear. You can even cast Seduction while stuneed, useful to control a rogue that Cheap Shots you out of stealth.

Just keep in mind that while leveling on a pvp realm, it's useful to get a few points in Suppression, so you can handle higher level gankers. DoTs, Drains, Fear, and Seduction are all more likely to miss if the ganker is higher level than you. I remember the goold old days back in my 30s in STV, I was able to take down gankers 3-4 levels higher than me Seduce Nuking & Fear Kiting w/ maxed Suppression.
