I love the conversation surrounding this.
Archmage Khadgar says: … You’re entrusting a goblin to be your foreman?
Thrall says: Gazlowe oversaw the construction of Orgimmar.
Gazlowe says: Orgrimmar! The impenetrable fortress!
Archmage Khadgar says: Wasn’t it recently sacked?
Gazlowe says: Yeah yeah. Okay, one little sacking.
