I’m not even sure he’s talking about the duel specifically. The shit Hellscream did to the Tauren in Tides of War could be seen as betraying Cairne Bloodhoof 

But he specifically stated “betrayed my father”, which would in fact refer to the duel. Anything past that part would be in regards to Baine because none of the shit Garrosh pulls in ToW or onward were while Baine was Chieftain

Kind of, but what I mean is that Baine is essentially saying “my father joined the Horde in good faith; and you’re just shitting all over that, Hellscream”

wait now I need to make that into an image like the one I have of Nazgrim

Tauren speak in Times New Roman, of course.

Also: who has complained to Fargo on Twitter?
