Pet Defensive stance change

We recently changed the way defensive stance works for pets. In the old design, the pet would not attack a target that you were attacking until it did something to generate threat - typically attacking you. In the new design, as soon as you attack a target, the pet will attack the target too. Our thinking was that this made defensive a little easier to use and you still have passive to override that behavior.

However, we have heard from some players (hunters mostly, though this isn't just a hunter issue) that they prefer the old defensive stance. We wanted to get a little more feedback from players on the issue.

In order to keep this readable, please don't stray into other hunter or pet issues that don't directly affect this topic. Also please don't attempt to redesign the feature (such as having four stances).
