So, I briefly though about alliance and more evil ways. IMO we have in the story so far:
- Tess Graymane as a much more agressing leader (potentially) than Genn
- Alleria going wild if something happens with her family
- after Anduin declined the request of Tyrande, night elves might feel betrayed and come to realization, that maybe there was a point in the Empire and start moving to embrasing the old ways
- dwarfs are easy to provoke, and iirc some were on board with attacking the horde, so they might be easy to hop on the “hype train”.
- Anduin giving into the void.
And if something “morally grey” is needed, we have story about Night Warrion carving out the elven Empire. Which means… if Azshara knows a way to live through the ritual, Malfurion might face a choice: here is a person he hates, passionately, yet she might be able to save the love of his life… And where could that go, with night elves starting to see Azshara as someone to bargain with, not too hard to imagine.
It just does not have to require placing Turalyon on the edge of being out of character, there is enough of it in the story as is IMO.
But who knows how the devs see it all.
