So I am leveling like everyone else, and I figured that I would pull out my old voidwalker rather than face-tanking while leveling. Soon I realized that the voidwalker is HORRIBLE at everything it does. It fails at every aspect of being a pet, mainly at being the tank that it is supposed to be. It cannot hold aggro through more than Siphon Life, and the other abilities are a joke. I am not even convinced that the AoE taunt causes aggro. Health funnel heals for roughly twice that of Devour Shadows, and the bubble... well, it might be useful if it didn't take up my pet and reagents, and time, and etc...
So, is there any hope for a voidwalker being a halfway useful tanking pet, or is my only hope speccing demonology for a felguard?
