I would like the worgen to retake what remain of Gilneas, if just to spark some battles between Gil and Silverpine.
Regarding Stromgarde, forget it. The Forsaken have been nearly unstoppable in conquering Hillsbrad, Silverpine, Tirisfal, and Arathi. The Horde may lose their hold on Arathi, they only have it because of lack of resistance, but reclaiming the ruined city wouldn't even fit with the lore. The humans all but abandoned Strom to build Stormwind (clever naming, btw). They wouldn't want to take it back, it can't support itself as a kingdom, and would require supplies. Plus the Horde would no doubt raid any emerging settlements and it would take massive rebuilding efforts to make the place livable. I know the place is close to the hearts of all you diehard Vanilla people, but it's been over for a while, even when the Trollbane's were still alive.
However, responding to the above proposals:
I actually wouldn't mind a truly neutral town. It's central enough in the continent to be busy, yet far enough from anything else to avoid any major attemts at a conquer. Just don't make it like Dalaran, that place drives me out of my mind. It's one thing to have those damn Silvers flaunted in my face, but the whole sense of denial the Kirin Tor imposes on the city is maddening. It's a sancuary vs neutral debate. Unable to attack, or able to attack after which you are killed by guards. I vote for the latter.
Whoever wanted the Alliance to obliterate the Foraken, not a chance in Hell. Their assualt has been too perfect to warrant a complete turn-around, and Sylvanas is too strong a character. She's the development team's pet project, they all favor her and she's an incredibly controversial character. Hated and loved on both factions, they need to be really careful messing with her. Remember how they almost killed her off? They had to bring her back of course. I'm not complaining, just telling you that you're out of your mind.
