I really have a hard time grasping how anyone could have thought it would be a great idea to basically repeat the same plot with so many characters on the same side adapting similiar role(s).
You have:
Sylvanas as Garrosh
Saurfang opposing Garrosh / Sylvanas
Baine complaining about Garrosh / Sylvanas
Anduin replacing his Father and Garrosh / Sylvanas counterpart.
Genn having a hateboner for Sylvanas
Jaine having a hateboner for the Horde
The irony of this situation is that the greatest change is that Sylvanas became Warchief, nothing else, no new motivations / PoV, nothing.
I mean think about it, that's like Lucas remaking A Phantom Menance but changing nothing besides the actor of Darth Maul and doubling the runtime of every single council / round table discussion scene.
How about some Tortollan complaining about overpopulation?
