A story of loss is not always a bad story. My main is Alliance, but I also went back and played through the 1-60 content as a worgen. I loved the story, even being on the side suffering losses. The tension felt palpable and left me absorbed in the story, determined to go beat !@# with each quest I embarked on.
Its not always a bad story, its just not always a good one either. I think that a lot of people just want to see or hear an inkling of whats going to happen here. You can not even hope to dissuade the Alliance players from the simple facts. 1) There is an overwhelming public Horde Bias that is perpetrated not necessarily by you and Bashiok (and the other CMs) on the forums, but by the developers and other employees while putting on Blizzcon. Each year we are inundated with imagery and action that perpetrates this image. It may not be fact, but it is the public face you as a company put on. (If you want anymore proof of that, just go and look at the public apology that had to be given this week over the Lvl90ETauren concert.)
2) That there was not battle after battle fought both in game, and "during the cataclysm events" that have not gone the Alliance's way. While the Alliance incurred a little into Southern Barrens and actually started construction on a keep in Swamp of Sorrows, we saw these as our only movement in an expansion that was marked with war and destruction across the entire world. We saw the siege of Astranaar, the destruction of our flight path in Azshara, the overtaking of Gilneas and the entirety of Hilsbrandt. We even saw the rout of Alliance forces in Western Plaguelands/Andorhal. We even saw the horde expand their reach in Blasted Lands, build a proper "fortress" in Badlands (yes I realize its undersiege by dragons, but its there.) We even saw the complete destruction (nuclear) of another Alliance area.
Yes there is something to be said about story and how it needs to play out, but during all this time, we have been like a battered wife/husband, just coming home day after day and enduring the beatings. You release this information in interviews and do not do it with any context that is required. If you had simply said, "theramore is going to be a focal point of the preMoP RedvBlue war event," no one would ahve said a word other than "omg cool". Instead, once again the PR people didn't do their job and released it in the wrong way, using the wrong wording, and you are here just making it worse. Even if I would love to hear what is to come, I would just love it if you said, "we are done talking about this" and walk away. Hell, I would love if this event was not even run on the PTR so we can see it as it happens instead of it being ruined 2 months before hand like so many things in the game have become.
(As to that, I would really like to see the interesting content, especially raid content, not on the ptr. We'd rather see, slightly over the top difficult encounters with some bugs, rather than watch the elite and middle of the road, know the encounters like they were farm content come night 1.)
