Now that the end of the expansion is here and we see the Tyrande vs. Sylavanas saga end in "renewal", I have to ask:
How would the story have changed if Tyrande never became The Night Warrior?
I'm been recalling what would have changed if she never became "Elune's Wrath", and the answer is... not much.
- There was the Darkshore warfront, but after running several of those I don't recall Tyrande playing a part in the Night Elves canonically winning.
- There was the infamous questline where we first saw THE UNBRIDLED MIGHT of the Night Warrior unleashed upon a human archer... and fail to kill him. So if Normal Tyrande just showed up and shot a few arrows, the effect would be the same. The only tangible effect was one dead Valkyrie, so the "heroes" would later face 10 of them in Sanctum of Domination instead of nine.
- She ran headfirst into The Maw before anyone else did, but I'm doing the Night Fae campaign questline now to see what she got up to. Turns out all she did was kill a bunch of Torghast trash. She didn't even rescue any lost Teldrassil souls; we did that. After catching up to her, Shandris explained how we had the soul crystal and could scoop them up, which we did three at a time thanks to a weekly quest from Yserra. But we would've done that anyway, and now Sylvanas is doing that, so no change there.
- When Sylvanas lead an assault on Ardenweald to get the sigil, Tyrande did NOT take her down, and Anduin walked in while none of us were looking and snagged it. So Normal Tyrande wouldn't have changed anything there either.
- Elune popped after to chat with The Winter Queen and forge a new sigil during Tyrande's depowering, but that didn't require the ritual. Elune could have dropped by any time.
- And now the post-Jailer defeat epilogue is here, and Tyrande tells Sylvanas to jump in the Maw and start doing Soul Retrival yearly quests. Normal Tyrande could still do that.
So... what did the Night Warrior do to effect the Shadowlands plot?
Aside from landing the killing on Nathanos. But frankly, Azeroth's murderhobos probably could've done that, too.
So if Tyrande just stayed normal but pissed off, and the entire Night Warrior plotline was scrapped from BfA, would it have mattered?
