The story would be more interesting but i don't think the writers know how to go about this considering the entire plot of BFA had a faction war element to it 'bringing it back to warcrafts core' they try to sell it as, if we have to follow this idea you have to understand that in warcraft 1 and 2 the horde was the evil faction, from warcraft 3 onward we started to only just see them in a more noble tribe light, this was later all written off as the horde being under the control of the fell bloodlust and gul'dan.
All in all the game does not do a good job of telling the whole story, it's disconnected as it jumps all over the place. We are always going back and forward in time sometimes even into the future or alternative realities. If you didn't play every expansion fully it is rather hard to get the entire story.
Nobel (sp) does a fairly good job at it.
tl;dr: BFA design philosophy "bring the war back to warcraft" "Original warcraft games the horde were the bad guys".
