The war that raged in Cataclysm was declared by a Varian (and fanned by the Twilight Hammer), after he blamed the entire Horde for Putress and Varimathras.
So, regardless of how willing the Horde was to engage in it, they weren’t the ones that outright started it.
As I said, from that point onward it was either fight or die. Regardless of how negative said consequences were for the Alliance.
And Varian decided that the best course of action regarding Yogg Saron was to let him kill them all.
Nobody is spotless, and arguing for genocide is never reasonable.
Specially regarding people that helped the world and saved it repeatedly.
There is an exhaustive list of “kills” in Chronicles Vol.3.
And that’s not counting Thralls role in Cataclysm.
Legion started on a note that had the Alliance intelligence leading both sides into a trap that killed the Hordes Warchief.
And still, regardless of the amount of clarification given, they are the ones pissy about some perceived abandonment after hearing a retreat horn??
Blizzard doesn’t need either. They used Sylvanas as a mouthpiece for a list of grudges that were left unanswered.
Whats the Alliance motivation? Theramore? Gilneas? The one that ordered such is dead. As are his apologists.
The motives Yrel has, have nothing to do with anything the Iron Horde did.
They even call them friends.
