Genn’s actions in Stormheim could have led to a nuanced faction war.
I as an Alliance player have a ton of arguments I could toss out to excuse and downplay Genn’s actions, and allegories to compare them to Horde actions to push the point that the Horde is still far worse even if Genn did do wrong (which is an admittance that the first line of arguments didn’t work, but this being a fight on the internet, I will loudly deny that I had to concede anything) - but, ultimately, it was a bad (if understandable) move on Genn’s part.
…But then Blizzard decided to turn Horde villainy up to 11 in the very first act of the faction war expansion.
