Hmm, see, I want to be cynical about this, but besides the obvious keypoints (saurfang was either gonna die or become another warchief with a boulder on his shoulder), it was always clear that this whole mess could never be resolved in any decent manner. In that regard Saurfang dying to show everyone their warchief's true side was the ultimate play, Sylvanas was already cornered, her just fleeing the battle field after holding her impotent cunty speech was about as much as could be done here.
Also the setting certainly looks bad for most leaks, which is also something positive to take from this .
