Blizz never really showed the Horde mending fences after Garrosh's bout of Orcish supremacy... nor the Forsaken patching things up with others after Wrathgate... or the recent mess with Sylvanas and BFA.
How would you all have the Horde patch things up after all this mess when we return after Shadowlands?
My thoughts...
1. Forsaken help cure Red Pox or Blood Plague among the Orcs and Trolls. Or some new disease among the various tauren societies. Playing up their medical angle.
2. Trolls, especially Revantusk, try to help the Forsaken or belfs hold onto territory in northern EK against resurgent stromgarde.
3. Orcs help Zandalari resettle Nazmir or other old troll territories, maybe help Darkspear set up more towns throughout Kalimdor? Especially around the Barrens Oasis's.
