It’s amazing how many people fail to see this.
The context is that Saurfang and Sylvanas are making their last stand in Lordaeron. Saurfang says he wants to stay and fight to the death (it’s what orcs do) and Sylvanas gets pissed at him because Saurfang is being suicidal, again.
She tells him that honor means nothing to someone like her, and unless he wants to die in vain, it’s better to retreat and fight another day instead of yelling lok’tar ogar all the time.
So she has a point, but as usual she said it in her no chill Sylvanas way.
