As bad as the Burning of Teldrassil is in universe, it does need to be taken into perspective.
The Burning of Teldrassil was not the Armenian genocide or Hiroshima bombing. It’s the Snappening. It’s the Death Star blowing up Alderaan. It’s the fall of Reach. It’s a moment played for darkness in drama in a franchise where having 90% of your species being wiped out is better known as Tuesday.
So yeah, I can totally see how you can acknowledge the Alliance is totally justified in being ticked off at the Horde while still making jokes about Teldrassil… because at the end of the day, it is just a game and nobody seriously thinks the folks at Blizzard promote actual genocide, right?
Right?
