Honestly it all depends on how they treat Azshara in the narrative, as an old night elf villain tied to their story, or as an adversary of Kul Tiras, or both. In all the years we’ve had building Azshara up, we’ve only ever had her encounter Malfurion, Illidan, or Tyrande once, that being when Malfurion confronts her in Darkshore, in a quest that’s nearly nine years old now.
I’m mentally preparing myself for her to be usurped as a human/Kul Tiran antagonist instead, with the night elves relegated to playing hot potato with Darkshore against the Forsaken. Because as it stands now, Farondis, and the Kul Tirans in general have had a more antagonistic build up with her in all of WoW’s history.
If they do include night elves, that brings up the other issue of which history Malf and Tyrande have with Azshara is the canon. In the Knaak canon, which was presumed the actual canon for many years, Malfurion and Tyrande barely interact with Azshara at all. In fact, I don’t think Malfurion ever actually meets her, and Tyrande’s interaction is all of five minutes. If that version of the War of the Ancients is canon, then Azshara would only know them as some wet behind the ears kids who foiled her grand plans in the space of a few months.
But, Blizzard has played fast and loose with that version, and they could very well be leaning towards the original canon of the War of the Ancients, which makes much more sense timeline wise. In the pre-Knaak canon, the war lasted for years, maybe even decades, and Malfurion, Tyrande, and Illidan were well known to Azshara and more than likely interacted many times, Illidan especially. That version ended with Azshara and Malfurion dueling each other at Zin Azshari, the battle so insane that it destabilized the Well all by itself, making Mafurion much more directly responsible for her defeat. However, the Warbringers short refutes that as well, as it shows the exact time Zin Azshari was flooded, so… no clue.
If she’s going to kill anyone, it should be Malfurion. And I’ll gladly sacrifice him if it means we get night elf involvement and we also get confirmation that the Knaak version of WoTA is retconned forever because it’s… it’s really bad.
So bad.
