Well, the Night Elves refused to aid the Tauren against the Centaurs despite the Centaurs existence being from their beloved demigode and also having the Tauren telling them it would lead to their own extinction. They made their lone-final stand and then were saved by the Orcish people & made their blood pact. So I think Night Elves being angry at Tauren is hypocritical"Oh so NOW you care about genocide!? When it’s your OWN people. I see, I see … Interesting. "
The Tauren originally learned it from Cenarius who were seperated from those ways after the Sundering, which was later rediscovered by the aid of Malfurion. I’d hardly call that a treaty of allegiance though / much of a ‘betrayal’.
Extremely Damaged / Ruined, I’d say yes - Destroyed? Not quite (Hanging by threads I’d wager though) the Horde are still helping Azeroth and following the leaders combined efforts to face off dire threats etc; but I will say it ruined the purity of the hero fantasy. HEAPS of players, myself included were finally looking forward to have Blizz apply the villain bat to the Alliance for once leading up to BFA but they applied it to the Horde … Again … And straight up LIED to us in Blizzcon AND Questionnaires - Multiple times.
I’m hoping for some developed story between various racial factions and not just ‘Horde / Alliance’ because it seems rather lazy. I’d like to see more depth from other characters in X race and not just have their leader speak for them entirely, like Blizzard try do with the Tauren people through Baine Scapegoathoof.
The implication is that the tauren ever reached out to them-- or had the ability to. They were separated by leagues of treacherous land and the night elves were entirely insular and stayed in their forests. The druids hadn’t been reawakened to have that bonding facet, either (and tauren druids weren’t pulled out of Blizz’s backside yet).
And it’s not for lack of want. The night elves in WC3 aid pretty much everyone who asks (mostly in the form of furbolgs and blood elves). Despite the way they stick to themselves, they don’t turn up their noses to potential allies.
The only interesting thing here is you thinking that not helping with fighting a foe, for reasons we don’t know, is just as bad as actively participating in a genocide. That is indeed interesting.
When not helping a person fight a foe that’ll lead to a entire races extinction? Yeah that’s pretty interesting, especially since the centaur wouldn’t have stopped at the Tauren.
