Combat Guardian

There is a Horde quest available Survey the Lakeshore - Quest that gives you which provides a guardian combat pet Surveyor's Beacon - Item that is usable anywhere, including BGs.

This pet doesn't hit for much, but will provide pushback, chase after stealthed classes, and interrupt bandages. As well, if your enemies use nameplates, it will add an additional piece of confusion to the battlefield.

Because it is a guardian, you can have it in addition to your regular pet.

Enjoy your little goblin wench!
