And the immediate response was to declare war on the Horde.
A situation that was deflated if I remember correctly, because further down the line it was proven that it was the Twilight Hammers doing to cause division.
And the Alliance retaliate instantly by invading Undercity, killing Putress, and having the Night elves cut all wood access on Ashenvale for the Horde. Instant retribution.
Not sure if you are talking here about Cataclysm or BfA.
Regarding the former, the Alliance invaded the Barrens in response. To the point they went after Mulgore and Durotar too.
If it’s about the later, this came as a response of what I already said a few posts above.
Doubt this counts as an actual act of aggression that went unanswered, as it was part of an ongoing war between both factions. They were already killing each other across the globe.
In short, all the examples named had the Alliance instantly reacting with an equatable response. While Stormheim was left hanging while the plot address bigger things like the Legion invasion.
Yeah, kind of derailing it. I’ll stop now. My bad.
