As for the rest... Hypothetically, if the Alliance were to seize Orgrimmar & risk a full-on war with the Horde whom they're fighting WITH in Org, the Blood Elves & Forsaken would obviously become involved. They would have two basic options: sail West and meet the Alliance at Org or march straight South. Either way, the required amount of Alliance forces it would take to hold a battered and largely broken down Org falling the siege and removal of Garrosh against both the Tauren & Goblins (who live nearby) would be tremendous & considering all Alliance forces (even the Night Elves) essentially have to sail there and are bottle-necked all over the place, holding Org would be a disaster for the Alliance. If the Blood Elves & Forsaken did march South, the Alliance would be in A LOT of trouble. Sylvannas WANTS some opposition. Her best bet would be to cause mass casualties via plague & whatever and use the fallen Alliance as soldiers for the Forsaken / Horde via her Val'kyr.
Just the logistics the Alliance would need to overcome to occupy & hold Org would basically put the Horde & Alliance on even footing (perhaps even in Horde favor).
