Such as?
The leak where Sylvanas takes Stormwind and it becomes a raid? That leak?
The leak where Stormwind Harbour is attacked by ghost ships and we all die and go to the Shadowlands? That leak?
Or maybe it was the leaks that literally threw as much shit as possible to see how much could stick, most of which was related to stuff that we either knew was going to happen or stuff so obvious that there was basically no other choice.
The same "leaks" will happen again involving one or more of the following:
Dragon Isles
Dragonsworn Class
Tinker Class
South Sea Isles inc Plunder Bay
World Rebuild
Cross Faction
X,Y,Z as playable race
Void Lords
Ogre Continent on Draenor
Silithus Sword 'fix'
Meet Azeroth Titan
It's interesting how with all these "super accurate leaks" everyone conveniently forgets all the shit that was just completely wrong.
