If I had complete control and the only thing I couldn’t change was the burning?
I would’ve preferred the Fourth War and the Kul Tiras/Zandalari story to have been separate stories. Maybe in the same expansion but self contained with one setting up the next.
As an example. Say the War of Thorns doesn’t happen right off the bat. Let’s say the war already kicked off in Silithus in a battle over the azerite but some third party, possibly what is left of the Aspects or some watchers, basically tell us to back the Hell off from Azeroth’s bleeding wound and fight our war elsewhere.
Then we find out there’s a BUTT LOAD of azerite in Zandalar. Why? Because Zandalar is a holy place similar to Mount Hyjal. Wild gods, avatars of life and nature, congregate there. Therefore there’s something special about those mountains.
Horde goes there to try and sweet talk Zandalar into mining azerite from their sacred mountains. Something that King Rastakhan is NOT on board with.
Alliance go to Zandalar’s closest neighbor, Kul Tiras, and convince them to go to war with their long time enemies the Zandalari and use their nation as a spring board to fight the Horde over a war for Zandalar’s azerite.
The two powers fight a proxy war through the two nations. it escalates. Somewhere along the way the War of Thorns and Battle for Lordaeron happen. Suddenly what started as a small, local war between the two premiere naval powers with the backing of the global superpowers turns into an all out world war.
So we’d level in Kul Tiras and Zandalar and do that whole song and dance. Afterwards we lead into the Fourth War and it opens up with large, cata-style revamp of Darkshore, Ashenvale, Tirisfal, and maybe Gilneas as we fight over those areas.
Then as the patches roll out they introduce new regions like Arathi or the Barrens.
That is how I’d do a pure faction war story that doesn’t leave a chunk of the playerbase going “Okay but what is my motivation?”
