I swear to god if they pull the whole old gods did it and reset to the same status quo of Alliance and Horde are at kind of peace but they still hate each other I'm going to completely swear off any interest in the story. It's time to end this conflict it was old news 15 years ago, you can't just keep on repeating the same story line without actually accomplishing anything. The entire history of the Alliance and the Horde in WoW can be described in terms of two states, kind of at peace but still hate each other and apocalypticly stupid.
Vanilla: Peace, except all the minor skirmishes
TBC: The same
Wrath: The same until Wrath gate then stupid
Cataclysm: Stupid
MoP: Stupid until SoO
WoD: Peace
Legion: Peace until Broken Shore then stupid.
At least thus far we've managed to actually keep the major war to a time where there is an impending apocalypse, well that is until Azshara shows up and makes it incredibly stupid again. Like in the real world wars don't tend to repeat themselves unless someone gains something, and has there ever been an Alliance versus Horde war since the RTS games where people haven't outright lost things? Like Theramore was lost but it's not like there is a Horde city there it's just a smoking crater.
