Flying straight into Icecrown would be suicidal. The aspects are powerful, but as I said they can still be brought down by hordes of frost dragons and gargoyles. The wild gods are really not that strong. Cenarius was killed by Grommash, the loa in Zandalar fell like flies. Rezan, Shadra, the bat guy, all dead in pretty quick and generic ways.
Also, if the Lich King won, it remains to be seen if Deathwing would awaken. Chronicles says that N'Zoth awakened Deathwing only because he sensed a window of opportunity to strike after the Lich King's defeat. If the Lich King never lost,
The biggest threat of the Lich King is that he controlled an army that could wash over the world like a swarm of locusts. Luckily the good Arthas was keeping the Lich King at bay. Now that there's no Lich King, the mindless Scourge poses a threat to the entirety of Azeroth, as we can see in the pre-patch of the next expansion.
