Maybe I'm not as jaded as some of you here, but I would like to believe the writers knows better than to give us an exact rehash of Garrosh' ending.
Garrosh was handled really poor. They had the opportunity to show nuance by actually showing a struggling horde due to Cataclysm and it being the sole reason for a war between the Horde and Alliance. But in-game reflected that very poorly where horde showed no sigs of struggle (Orc clone machine and several fortresses and outposts with no logical supply lines). The writers miscommunication about the character of Garrosh was also pretty horrible. His character arc told by the stories released at WoTLK was ignored and he was firmly sat to become a dictator. Instead of becoming a second Orgrim, he became blackhand.
The worst offender was the final bits of SoO where horde as whole did not get an introspection of their culture. Everything was placed on Garrosh and their own compliance to the war up to mid MoP was also blamed on Garrosh.
