Pack Hobgoblin

If you like the idea, but you don't want to roll a Goblin, simply go and start doing Argent Tournament dailies. The reward is almost the same.

Rarely-realized fact: Gobber fears nothing and can be summoned in the middle of combat. Useful if one of your weapons breaks or if you suddenly realize you left your Volcanic Potion in your other pants.

For dual role classes(classes that can dps and tank/heal ie paladin), this is incredibly useful, as you don't have to waste bag space carrying your off spec armor in your bag; you can just keep it banked and use this handy ability whenever you need to change roles.
