Regardless of how “villainous” they might have appeared, which they really weren’t, the Night elves actions were completely uncalled for and entirely insensitive to the fate the Blood Elves were struggling to face. The only reason I bring this up is because you’re sitting here kicking your feet crying “but mah tree!” when Night elves gave no such sympathy to those who faced the same crisis.
You seem to be missing the point entirely. It was the relationship between the Eredar and Draenei that led to the legion chasing them to Draenor in the first place, Sargeras even refers to Kil’jaeden’s pursuit of the Draenei a personal grudge that he had no interest in. The Draenei settled on an inhabited planet, endangering not just themselves but the indigenous life already living their, and the very planet itself. They didn’t even bother warning the Orcs of the legion during their time there either.
It seems strange that you’re so quick to exonerate the Draenei for their acts, but blame the Orcs for being unwitting victims of the legion and making them out to be blood-thirsty killers when after the effects of the demon blood wore off many were stricken with grief over what they had done. It’s been the driving narrative of Saurfang this entire expansion actually.
What is, and isn’t retconned is pretty irrelevant considering that only current canon events are relevant. I’m not gonna sit here citing lore from the RPGs, and then tell people it was retconned as an argument when people tell me that it’s not current lore. Yeah retcons suck, but you can either swallow that bitter pill, or avoid bringing it up.
Are you referring to one small order draining M’uru? Even though Blood elf society at large condemned the act, and saw it as immortal. Even the Farstriders protested the idea. And yet the Night elves actions weren’t to rectify what the Blood knights were doing, they were there to cruelly preying on the elves in their moment of weakness.
It’s less about wanting sympathy, than being shocked that you’re trying to play the high road card after taking part in such atrocious behavior when another race was faced with the same dilemma.
I mean, the Horde and Alliance were on an active truce, but it was Alliance agents killing the Horde goblins for mining Azerite before any actual war broke out. Truces only last as long as the peace does after all.
The blood elves first had to “forcibly” remove Night elves from Silvermoon city, then in the ghostlands the Night elves take over settlments that force the Blood elves to combat with them once again. There’s a questline in the ghostlands where you, and some blood elves are literally ambushed by Night elves. “eradicating” is not the word I’d use, but they certainly picked an interesting time to invade their lands and engage in combat with them.
In addition to all this the Night elves then send a Dwarf to Silvermoon under the false pretense of establishing an alliance with them, but then use him to get detailed schematics of the Sanctums to which they then use to sabotage it. A vital source of magic they were using to battle off the scourge.
You really have no place to be telling anyone to feel bad about your tree after all that. Not to mention after this whole “Night warrior” business with Tyrande, we’re only likely to see more and more scrupulous behavior from her and the Night elves that will likely end up in spilled blood from both the Alliance and Horde sides. But I guess we’ll have to see.
