I get ya - also I think, culture-wise, it’s such a neat combo. You have the orcs, who have always been raised to be tough, to always keep your guard up in every respect, and to channel your negative emotions into strength - and that strength keeps you alive.
Then you have the Pandaren, whose entire culture is based upon understanding conflict and resolving it. Not just burying it - dealing with it. Confronting it.
I can absolutely imagine an Orcish soldier traveling with a pandaren one, slowly opening up, and learning to draw his strength from places other than hatred and fear.
