The High King has been in the Shadowlands for 5 ingame-years now (though I guess for the last 3 years timey-wimey stuff is possible to make it more or less than that from his perspective). That’s quite a bit longer than his 3-year rule as a king was - indeed, Turalyon has held the Throne for longer than Anduin did.
Anduin spent the first 2 years of that as a stubborn and unbroken prisoner, until he was mind controlled to do a Lich King cosplay. Embarassed about that, and a bit put out by that murdering and plundering throughout space afterlife, and maybe even liking the memory of the dark powers that he wielded a little too much, he decided that he needed some time to heal his soul. So of course he joined the genocidal lunatic that was responsible for the violation of his mind in the most depressing place in the universe, the Maw. I’m sure that little bit of therapy will have him sane and happy in no time. Let’s hope he didn’t linger there too long, since we have no idea how much time he wasted there, and if he went somewhere else after that. We haven’t heard from him since.
Before that, Anduin’s presence in the game had become pretty dominating. In a story based on the factions, he became the (somehow) undisputed commander of the only faction that didn’t fight itself, and over the years he made a habit of explaining how the world and morality works to a bunch of old white people, like any good millenial new to a leadership position would. If you wanted to know what the Devs wanted the player to think about an issue, you’d only have to look at Anduin’s take on it, since it had a negligible chance of being wrong.
So… Considering he will likely be back at some point, and likely back in the spotlight, when he returns… Any suggenstions of how they could write him after this to not make him suck? Will we have to suffer through some kind of “I am a monster!”-drama because he couldn’t shake his Arthas-phase? Will he become another wise space wizard with a similar role to Medivh or Khadgar, there to give us exposition about space stuff and deus ex us out of any pinch? Will he come back to stop the evil Turalyon from selling the Alliance to the invasion force of the Light, giving us an Alliance civil war, where we will be allowed to side with Anduin, whose moral position is once again the obviously right one?
Or does anyone have an idea that might actually be kinda cool, or might even make him more likeable after his ordeals?
