That's what I'm saying though, "Awakenings" can't be as significant or specific in-game, because the fact that it is plural immediately means it's talking about a bunch of different events.
The point is not that the title is ultra unique only something that can only make sense in Warcraft; you could have a Wrath of a Lich King in any fantasy game that has Liches, or a Legion in any IP that has a notable army. The point is that the titles are always very specific and singular, never something vague and ill-defined or difficult to pin down. Which is what "Awakenings" is.
A player interested in a revamp expansion made up a title they figured sounded mysterious and grandiose, that was more metaphor than anything else and fit in with the revamp/rebirth concept. But Blizzard coming up with a title isn't looking for mysteriousness, they want clear definition that communicates as much about expansion as possible in a few words that sound nice together. You can see this with MoP. MoP is an expansion that leans heavy into mystery, and even then, when trying to capture that sense of mystery, they picked a title that communicates that mystery AND specifies what the expansion is: Mists of Pandaria. They don't do floaty abstract titles, which is exactly what "Awakenings" is.
Like I said in the last post, if it were grounded in specificity, maybe; "The Awakening" (no plural), "The Great Awakening", "Awakening of Azeroth", "The Last Awakening". But Awakenings just isn't the expansion title style.
Why would he care about the factions on Azeroth? The primary threats to his agenda are all in the Shadowlands and also the Alliance is only one of the strongest factions on Azeroth when dealing with Azeroth tier threats they can mobilize a regular army against. There are clearly much, much bigger potential hazards to his agenda and defenders of the planet, like the Watchers of Ulduar, the Dragonflights, the Kirin Tor.
Also attacking Stormwind would literally only distract us. That is, the (Alliance) players and like half a dozen leader NPCs currently involved. The covenants would still be focused on hunting him down, not worrying over a single city being razed.
