So from the results of this war:
Alliance lose Theramore, but regain Dalaran and the Kirin Tor.
The Horde lose Garrosh and, (SHOULD) be replaced by Basic Campfire
Honestly, I believe The Horde got the better end of the stick. The Alliance had an exchange for cities, while The Horde got rid of a racist dictator that was a stone throws distance from the demon-blood drinking horde.
The war-front on Pandaria, at first glance, is a draw, but the Alliance achieved their war goal of keeping the Horde from painting the continent red, which the Horde failed to do.
If the rumors are true, this war should've been bloodier, especially since I remember Sky Admiral Rodgers is one for vengeance, (surprised she didn't get on the chopping block for it too) to show we're too weak and need to focus on ridding the dermons from err lernds, by the hand of Neutral Turalyon and Alleria, with Med'an leading the charge as Thrall's apprentice, (Horde fanbois are screeching with joy).
What would've been reasonable is to have a similar event like Theramore, but not as a crater, and more of a ruins in say, patch 5.2.
This shows both a progression of story with very little work to actually put out, and gives the Alliance a sense of victory, while enticing the thought of rebellion into the Horde players as a means of survival, and not just because Metzen said so. The Alliance were never the good guys. We're all a shade of grey. Atrocities work both ways, and would make more sense lore wise for increasing rebellion within the Horde, as people usually tend to disagree violently when the war begins to come to their shores, especially in an ugly way.Sky-Admiral Rodgers takes The Skyfire and the 105th Alliance Navy division out to "disable" The Horde's large ranged missile capabilities and their center of Naval production in Kalimdor, effectively putting a Quarantine on the continent by conventional means. Garrosh meanwhile gathers the 114th Air division, ( I don't know military ranks, don't flame me breh) with 5-7 gunships spearheading the defense.
However, as a repeat of the twilight highlands quest chain for the horde, Goblin engineers and technicians fail to get most of the air fleet operational by the time the Alliance reach the Harbor, which the Alliance scenario starts and totally ransacks the place for any vital Intel, and obliterates the massive cannon. The hero, meanwhile, returns with a captive goblin captain, which is tied up and you listen in on the interrogation via radio, (which is not pleasant, and as brutal as would be by Garrosh or by the Kor'Kron). Meanwhile, you are sent onto a submarine to sink any Horde ships off the coast of Durotar, civilian or not, as to not raise any suspicion of the Ambush, then sent back to Stormwind telling Varian of the victory and the secrets you've learned. You're also told not to speak of the actions of Rodgers, as they get what they deserve).
The Horde one can start when the skeleton force left behind gets cleaned up by the Horde fleet, but the orcish captain of, say the right flank, sees a lone transport and gets cocky and pulls off to finish it off while you went in to scout of the ruins of the town. Suddenly, Alliance ambush off the coast. The Alliance never retreated, and the Horde fell right in. The Horde pull out, losing 4/5ths of the remaining fore in the process, running back into the gates of Orgrimmar with the shame of defeat. You, the hero, don't return, as spared by the Blood Elf leader of the entire division ports you to Silvermoon to hide out until Vol'jin is ready to spark rebellion, and is publically executed by the Warchief for his failure in the mission.
This one little thing would've left many Alliance satisfied, and not leaving the whole, "not the face" stigma that's been rampaging in TBC, Cata and MoP.
