Our point of disagreement here is the on the faction of honor lore characters. WoW doesn't really follow the story of the players, but instead really just has the player follow along. Most of the events that players experience in canon are done by the major lore NPCs, not players. Now this might have changed recently, but I don't think it has. Therefore, I think greater importance should be placed on what the major lore characters are doing and saying.
The list of disgruntled lore characters is getting larger and larger. In addition to Saurfang, we have Baine, Rexxar, Talanji, and Valtrois all expressing displeasure of some flavor about Sylvanas. With a new undead model of that one Blood Elf, we may see a point where even Lore'themar will oppose Sylvanas. Gallywix will pick which ever side he thinks will win, so can't count on him for any side here.
I guess you could consider this a different kind of unity. Unity against the leadership/Sylvanas.
