Aside from the one you guys have referenced in one way or another, for me it was this moment:
The second they turned Saurfang from one of my favourite characters, into another pawn of Goldens weird fetish with Anduin’s perfection.
When the Orc Overlord had to be taught of honour and motivation by a teenage human boy.
PS: Because would lie if i said i didn’t expect Baine to disappoint. Specially after i knew Golden was at the helm of the writing team.
