I think one of the most important parts of the Saurfang cinematic is that it does what MoP or Cata didn’t do well at all (and what was a major worry of mine after the Sylvanas Warbinger episode: it shows us the otherside of the Horde. The side that doesn’t blindly follow the Warchief. The other side that doubts the Horde and the side that still believes it can be something good even if it isn’t right now. It gives a sense of hope for the Horde, something to aspire and fight towards even while others go along with Sylvanas.
I hope we see more of this in-game in patches and the overall Horde plot. I want to keep this push going to have faith that it’ll work out.
It might just something of a retread of the whole “bastard jerkass Warchief” thing, but at least they have kept in mind to give Horde players who hate it that there’s still something to aspire towards with the Horde.
