I will give Az this though, he's right when he complains that the open world isn't affected enough. However, this was always a problem a WoW. I'm not defending it, but I am saying it's not just a WoW Legion or BFA thing. It's been a thing since TBC. Why weren't the Undead all across Azeroth during our quest in Northrend? Why did Deathwing stop attacking during Cata? Where was the Alliance/Horde War in MoP? Etc.
