From a warriors perspective. I use VB alot in PVP as well as PVE. VB provides +25% damage increase......basically as much as a damage elixir (25%) or better than any pet available out there. In addition, VB cooldown is pretty fast so you can use it after basically every mob you encounter. So.......for a warrior with VB there is basically minimal if any advantage of using a pet with increase damage passive? So sad.....
