I though the initial premise was good, Garrosh getting his revenge and giving the finger to the world, but then they killed off Garrosh and Zaela at the launch. It was a bit like Marvel with Endgame. Thanos was killed in the first 5 minutes so who is the enemy to fight at the end… Thanos again, but without any of the history.
I don’t know why the Legion was trying to corrupt the AU Orcs, and as more the game continues, the less sense sticking around makes, with the fading timeline thing.
If AU timelines are to be used again, the game needs some hard rules to follow. Right now, they don’t matter because there is some prime timeline, except for when some character pulls a plot device out to visit them again (Mag’har recruitment.)
