I suggest not using WCM HQ stream. It seems to make bad audio even worse.

I accidentally refer to health regeneration as mana a couple times. I am sorry for the mistake. Downloading this video will help you see how much health I am regenerating every 4.5 secs.

This video is not meant to show that 41/21 can take on 4 or more mobs, but to show that 41/21 can take on multiple mobs over and over again. This being done with out any FEARING (which spreads out loot-able corpse's), and no eating or drinking.

The idea for this build is nothing new. Anyone that played Warlock back before TBC can remember 30/21 (SM/DS) before DS was nerfed. Now that Fel Armor provides health regeneration, sacrificing a VW is now a great way to level.

With out going into a long explanation on DOT rotation, I'll simply say this... different scenarios call for different rotations. I usually prefer CoA, SL, Cor, UA. After UA, immediately follow up w/ CoA on next mob. Last mob gets no UA. This allows for UA to be replaced w/ Nightfall should one proc, mobs will die sooner, and UA's non GC does not go wasted.
