Full Disclosure eh, convoluted history, our world being plunged back into chaos? ... Bring it.
[Incoming fiction race bashing avert your eyes if you are easily offended by fictional race lore analysis]
What you'd rather be an Orc, whose every last clan leader was wiped out practically overnight in one expansion? A Troll (cause that's what your being) whose every last Clan Leader again has been wiped out in almost every expansion. Tauren or Goblin maybe, who basically just follow Orcs and Trolls for the giggles and whose leaders aren't known for any great accomplishments on their own. As far as Alliance races, as a Sin'Dorei I can say "F--K Alliance."
Sin'Dorei means Blood Elf. Their leader Kael'Thas made a Blood pact with his people he would get revenge on those who left his people to die and the Scourge responsible for the destruction of Silvermoon by any means necessary. He is betrayed by a racist human only after taking on the full force of the Scourge on the front lines. Leds a massive Prison Break quickly quickly owning the best security the best mages in Dalaran had to offer. In the secret mission they take on wave after Wave of Human, Dwarven, and even Pandaren forces only using Sin'Dorei enginner tower defenses alone. Oh yeah then they join forces with the Illidan another Unredeemed anti-hero who actually accomplish the job of truly conquering Draenor establishing absolute control over the land. The Orcs under Magtheridan work for them they sit on the council as the second most powerful boss in the expansion. Before you WoW babies knew him in Tempest Keep he was one of the few unsung/evil anti-heroes standing between Arthas and the Frozen throne, where as every other race was either unaware and cowering in their kingdoms while the world was at stake. Kael'Thas takes over an Interdimensional Naaru ship and sends Velen running for his life in the Exodar. (Nothing against him personally its just funny to think of celebrities crashing their expensive vehicles.) Kael'Thas sacrifices the fate of his people for more power but Lor'Themar step in to ensure his people survive and forms an even stronger force with the Sylvannas and the Horde. They later collect Pluck Kael'Thas out of his own fortress and the SunReavers collect his head but only after having to retake Tempest Keep and killing him in his seat of power. But before I finish this wall of text I would just like to mention that despite all thesethat they did survive, in with brains, guts and glory. THAT is what it means to be Sin'Dorei.tumultuous years finding ways to cope and survive
If you Prick us, we will Bleed you. If you wrong us, we will have revenge.
