But I don't think that a faction's going to feel left out here. The player group is probably the special task force of the invasion, and the Alliance and rebel Horde are working together, it's not one side leading the other, unless you really want to say the Alliance is following the Horde because the Horde members there actually know the place better, which is logical... but it's a partnership. The Alliance is providing a lot of the strength and the rebel Horde is providing the intel.
Not really, it's helping those oppressed under Garrosh get control back. The Horde's going to be significantly weakened by these events. That's a fact. The only strengthening they're going to get is a strengthening of their moral compass. That's it.
Any way you slice it, the Alliance is going to be the one on top after the Seige of Orgrimmar. The Horde as a whole will get a moral victory, but it certainly won't get a tactical one.
