In Combat

[olaruler455]

These:

Goblins in Orgrimmar that are workes and repair the city will attack you if you go close to them. This can help you if you are a hunter and you can use Disengage to get so some rare places. This also might work with Gobins in Booty bay if you are Hated.

Or you can just duel a friend for example.
