How can they keep Sylvanas relevant post-Shadowlands?

[Aleksej89]

Current story revolves around Anduin. We're in Shadowlands to save ANDUIN, Jailer wants ANDUIN and only him, Sylvanas gets owned by ANDUIN. Every character gets slowly turned into Anduin sycophant.

Sorry but i disagree.
Sylvanas started the genocides to feed the maw, she opened the portal to the maw and she is helping the jailer do whatever.
We are not in shadowlands to save anduin - we just want to kill/defeat the jailer. Anduin can die and it does not matter.
Jailer obviously has a fetish for light-wielding blonde boys considering both arthas and anduin are almost a carbon copy so stop kink shaming him.

Sylvanas does not get owned by anyone at any time for anything, her pet danuser makes sure of that...
Even in the last cutscene with the sword its all about her again, her past her feelings her decisions her thoughts her her her her her her...

Surely she cannot just die or become a blip in history. If they kill her, it would be the same as if they killed any other major classic character like Jaina or Thrall, or at least never hade them mentioned or shown again. Fans would go apeshit.

I really think Blizzard put themselves in a corner by making her a villain (at least we have further info on what's going on).

"Fans" would not go apeshit. Only Danuser would. We had way too much Sylvanas since Legion. Your memory might be a little foggy about this, but Sylvanas appeared in the last three xpac cinematic trailers...

Personally, I feel like she can die in a carcrash. Who in his right mind wouldn't wish a genocidal maniac gone...? Well, other than some edgy edgelords anyways.

The story revolves around Anduin.
Varock has an honor problem ... he's going to talk to Anduin.
The Horde has done a genocide to the Kaldorei ... It doesn't matter why Anduin forgives them.
The jailer has a plan so he needs prisoners ... He only has Anduin left and we give him two cinematics.
Sylvanas has a scene that would make sense with Dalarin or his sisters ... but not Anduin.

Anduin is getting into every possible place always providing the message of peace from him.

Literally the last cinematic is the same talk that Dalarin and Sylvanas had. With the difference that in Dalarin and Sylvanas it did make sense for Sylvanas to break down because that's where Arthas was turning. Sylvanas there was killing herself.

Now Sylvanas is far beyond Arthas. Why does it matter now that Anduin has mercy on her?

[Unbelievable]

She won't be killed off.

She will, either, end up like Azshara:
Queen Azshara says: Now go and do what you will. I tire of intermediaries and heralds. The true throne of power beckons, and I intend to claim it.
Azshara opens a Void portal behind her and disappears through it.

Or, like Illidan:
"As he dies, however, Illidan reminds her that 'the huntress is nothing without the hunt'."

"After Sargeras is defeated, Illidan takes control of his body and kills Gul'dan the same way Gul'dan killed Varian Wrynn, ripping him apart with fel energy until only his skull remains."

Blizzard seems to hint at that with the latest cinematic, showing her displaying some humanity:

Her role, after the Shadowlands, would be to train a new generation of Dark Rangers, and by doing so - introducing the Dark Ranger as part of the playable classes of WoW.

hopefuly by giving her a pretty gravestone
