I wanted to contribute something about the Amani-Highelf conflict:
Basically, I’m starting from scratch:
The beginning of the conflict between these two races was created over 10,000 years ago, it only intensified later, or rather escalated.
But because of Azshara’s contract two POV’s
The POV of the Highborne was that they have every right to every country. This was not just a thought, it was a matter of course, a state of mind that the Highborne took and presented to them. So Azshara just took what she liked, whether it was sacred to the other people, whether it was vital to the other people, it was irrelevant, she took it and nobody could do anything about it, because it was the sacred right of Azshara and the Highborne to do it. As we know, all of Azshara’s mentality went around the palace and the night elf people, and only the simplest of the common people kept a non-alienated view.
When the high elves finally landed in Tirisfall - already visibly changed, by the way - they still have this attitude. Many of the Highborne even wanted to take humans as slaves or otherwise integrate them as servants, only Dath’Remar refused to do so.
The Amani POV’s are the ones that the land grab was a deeply traumatic experience, because they were powerless, they could do nothing. When such elves appeared, who were similar to those they were powerless against, and settled down after nearly 3000 years, they saw it as a necessary act to prevent the traumatic experience and in consequence they attacked
Thereupon the attack on the high elves began, and yes, the amani killed the high elves as well, because they finally began to kill every Amani on sight out of fear of the attacks. Thereupon the Amani also began to kill the high elves again. So the Highborne travelled through the Amani Empire and found an abandoned ruin that was not used by anyone and built Silvermoon on it. But only when the city was completely finished and even the well was planted, the Amani suddenly attacked in huge flocks. The high elves did not want to leave what they had created and defended themselves.
Thereupon they destroyed a 10 to 1 superiority and in this conflict the first borders were created, there were border conflicts even after that, but all in all to neglect.
That was Elf-Fan-Service, just for your information, but in this story neither highborn nor Amani per se were described as bad or incomprehensible actions were committed. Both POV’s are justified and also logical.
Then there was almost 4000 years of peace, with some conflicts between Ranger and Amani. The Zandalari finally united the divided Amani tribe and made war possible in the first place. They called the Loa, summoned powerful spells, and used the sheer superiority of the Amani to launch an all-powerful attack that the elves could not counter.
Nothing to oppose? Here’s a little trip to prove to you that this is not an Elven fan service. The elves certainly had more than 100 mages, even better trained, so they could have just as easily summoned a fire devil behind their safe Sunwell barrier and could have wiped out the Amani there. In a logical story it wouldn’t have needed humans for that.
So why did they make the war the way it was, now, to give the humans an epic introduction. Just like the trolls with the great aqir war, the humans with the great troll war were properly established and introduced. They were the heroes of the great Troll War, and Strom was the great mighty empire, the elves needed help, could not make it without the humans, and so on.
In this conflict, however, the Trolls were ready to slaughter every Elf - and later every Human. And btw, the trolls had been hunting humans for a long time, even before the elves arrived, the trolls were hunting humans for food or for fun, there was a lot of hate in the game before that, that’s why Strom settled so far south.
Only the great Troll War and the Amani Mindset laid the final foundation for their downfall, when one experienced what a danger they could be to ALL the Eastern Kingdoms by trying to wipe out entire races, they themselves became the target of this mindset by keeping them deliberately decimated by controlling their population.
Trolls were hunted not for fun - which is a dangerous undertaking, by the way - but so that the great Troll War and what happened back then could never happen again.
