I just don’t know why they did it. The war of thorns ruined everything. It was lore wise the most supid thing they ever did, and the horde will forever carry this burden of being evil because Blizz refuses to continue on it.
Just like the Night Elves continue to feel like useless punching bags and the alliance itself feels like it has the mentality of a 5 year old child.
There would’ve been many ways to fix this. What if the horde character time traveled with the bronze dragonflight and helped evacuate all civilians in that event? That would surely help, the tree could still burn. That would be one option. There are several other ways to make the horde look less evil / a threat to this world, but Blizz simply needs to pick up this plot again and not pull a WoD 2.0 on it and pretend like it never happened.
