Yeah this is talked about all over the warlocks den. My main raider is a lock. I was always a huge affy/VW fan and tried the felguard in BC and hated it. Found that he did do more damage but couldn't hold aggro at all. Come WOTLK I did affy/vw again and I was much better geared and MUCH BETTER skilled and the vw was just useless. After listening to the die hard fans of the Felguard I tried the respec. I LOVED IT!!!!!!! The changes to then Felguard were amazing. The upgrades to his threat, the fact that every time I lifetap he gets mana, and then the addition of every bit of damage I do heals him then add on to the fact that he hits HARD. Granted some of these would work for the VW also, but the VW just can't do the threat nor the damage. My FG was critting for 1200+. Again, I was a huge fan of the vw but there is no denying that the Felguard is just king right now. I have no single box leveled two different warlocks to 80 with this method. Fantastic.

On a side note, the Felguard has also allowed me to solo things that I would not have been able to do with the VW.
