Due to these reasons, the wizards of the Kirin Tor had to take a temporary position of neutrality towards the Horde, to unite forces and deal with Malygos and Arthas. In addition, they moved their whole city to Northrend to be on the front line of battle.
At the time that these two threats be under control (in patch 3.3), the city of Dalaran will not make sense to stay in Northrend or remain neutral, so it should be arranged.
Also, to avoid having a ghost city more, and to reduce the lag that produces in so little space so many people, I suggest the following:
After having defeated the Blue dragonflight of Malygos and the Scourge of the Lich King in patch 3.3, the city is embroiled in an internal struggle for his control. On the one hand the Archmage Aethas Sunreaver that wants to take control of the magic city for the Blood Elves and the Horde, and on the other hand the Alliance led by Rhonin and his wife Vereesa Windrunner that, by not waiting for this treason, have taken refuge in the Violet Citadel, being stronger inside.
After an arduous struggle that lasts for weeks, the Alliance manages to gain control of the city again. Now the Kirin Tor has learned the lesson and the city of magicians will close its doors to the Horde. Since then the magical city will continue floating over Northrend.
In this way the city would cease to be a sanctuary and would be the hub of the Alliance in Northrend, but ... what about the Horde? The Horde should also have a great place to live in Northrend, maybe a troll style city in Zul'Drak.
Thus there would have two large cities on the continent of Northrend, one for the Horde and one for the Alliance, so the lag of a sanctuary city would disappear and also it would better adapted to the situation of the uncontrollable hatred between the Horde and the Alliance, though it might be possible even in case where necessary, a new sanctuary in Northrend run by Alexstrasza the Life-Binder and its dragonflight.
Even this would have more advantages: just leaving only one sanctuary city with portals to all capitals: Shattrath City, which would give him a breath of fresh air to this abandoned city.
