I leveled my lock most of the way in the destro tree just so I could jump in 5mans with friends and being an off toon I didn't want to put the money into dual spec. Well as I played more I became very fond of the class and I have started leveling him in earnest. There seemed to be quite a debate over the fastest leveling spec between demon and affliction, but for me it was no contest with affliction being much much faster. All the threads I read about people just tossing CoA and corruption and running around and watching the baddies die never made much sense to me as usually that will get an equal level opponent to about half health and if you dot enough of them try usually catch up. The best method I found was to start with that basic method running around and casting CoA and corruption on 5-7 mobs, stop running, and sacrifice your voidy (which as we all know doesn't kill them anymore, just provides a damage shield for us). Now with everybody dot'd and me safe in my shield we can cast rain of fire. If you are fighting mobs two three levels higher than you they won't quite be dead yet, so a instant howl of terror and reappy dots as the bad guys run...voilà . If this is done properly you, with a few strategic life taps in the rotation and the occasional death coil, you will experience zero down time and end up dropping 5 guys at once every thirtyoro 45 seconds. The health bonus off of corruption typically brings me to full health while I'm shielded so all I worry about is mp. The closest thing to slowing down that I have expirienced is when I have to fight one enemy or maybe two just to fill back up full on hp and mp. I've gone from 42 to 50 in four days applying this method and honestly only playing about two hours per day.
Thoughts?
