With the recent story development, and ptr and shadowlands spoilers, it becomes more clear than ever, that the mere existence of the Horde serves no purpose. They are a fake faction, build on fake honour, fake culture and fake values. The only reason it’s still existing after Battle for azeroth is gameplay.
You could delete it from the story altogether and nobody would notice any difference. Compared to all the other times we follow, mostly alliance aligned, heroes to defeat big bad guys.
So my suggestion is either dissolving both factions and become an united azeroth altogether with Anduin as Supreme leader. We can have Baine doing a symbolic gesture here by having him bending his knee to acknowledge the alliance getting authority over his dignity, soul, spine and body.
Or, if that doesen’t work out. Instead get the gang back together and make the Zandalari kingdom the ruling authority of their races. Everyone will become a subject of Empress Talanji and follows her just, enlighted and visionary rule. Even better. The former horde would finally get justified reason to stay in a cold war scenario with the alliance since the rekindled troll empire would love to see the currently alliance occupied troll lands coming back home.
I ain’t picky and would be happy with both of these scenarios.
He is awake, the problem is that he is not very bright, so he genuinely believes that the Zandalari can take on literally every other race on the planet when they could just barely defeat a cult worshipping an abnormal worm.
We zandalari rename the faction and take the leadership. Like this all former horde races can get an identity again that they can be proud of. Instead of the current mess that still makes no sense.
The Revantusk and Shatterspear can get zul’aman as their new home. If the sin’dorei keep paying their tribute to the empress, they will make good subjects the way it is.
From the Alliance side - right or wrong the only story-logically thing is for the Alliance to not accept peace and to continue to push for total victory over the horde:
Exile the orcs to outland permanently;
Amnesty for Tauran and trolls;
Peace with the Nightborne and blood elves;
Total and utter destruction of all undead
Sounds suspiciously like what I usually argue for… with a bit of an ironic spin/misrepresentation. Supreme leader Anduin, hm? Yeah, trolling isn’t obvious at all.
