If Horde quests were written like Alliance quests...
Then, during the climax of a world war, as the Alliance is heroically leading a last stand of rebellion against tyranny, the Horde would be secluded with spying on some tents outside of Stormwind using a robotic kitten:
The Alliance would be triumphant in war, as their enemies would burn and their cities would be razed to ash. Instead, the Horde would be scrambling to save as many burning civilians as they can, knowing that the majority cannot be saved and that their way of life has been destroyed, knowing they lost:
The Alliance would have the choice to take their own path. To choose whether to remain loyal to their faction, or perhaps to side with a more rebellious side. Meanwhile, the Horde would be stuck with one singular path predetermined by Blizzard:
Let's be real, what we are looking at is a clear, undeniable, and objective bias that Blizzard had towards the Horde quest writing.
They literally bent the rules of the game and introduced a Telltales system ("Zekhan will remember this") for the first time in the game, they did something unprecedented, just to give Horde players a choice.
Meanwhile, Kul Tiran players have no choice between helping Daelin's murderer free Cairne's son or just refusing to help them. Night elf players have no choice between helping Tyrande free Darkshore or help Anduin fight for Kul Tiras, a human kingdom they should not care about.

The fact that the Horde literally ROUNDED UP the civilians of a settlement in Ashenvale is some Galactic Empire level of horror.
I don't know how familiar you are with Star Wars, but in several scenes and videogames we see the Empire literally rounding up the civilians of a given settlement to torture/interrogate/execute them. That's why the Empire is so horrible. They have no problem with systematically hurting or slaughtering innocents.
The Horde is literally the Empire of WOW lol, they literally round up the innocent civilians of a peaceful settlement and mercilessly do horrible things to them.
