I don't see why pets shouldn't be included. Saying that some people have better pets and it would be an advantage? You could make the same complaint about gear...some folks got better gear so it's an advantage. No difference between the two in my opinion. I think it's one more thing that will make each character's build unique. We all have debates about which pet is better, so between having different skills, different passives, different gear, and different pets, PvP will actually be interesting rather than in PL where everyone uses the same exact build and gear for each class.
