Hot take, but I think Warcraft should end.
It's clear that the writers had a vague idea for the story of WoW. They'd first tackle Illidan and Arthas, and then there'd be the final war with the Legion.
That story has played out. The story took a few detours with rawr dragon, a faction war, and time traveling orcs. Some stuff didn't pay off as it should have (the titans). Most of the original people who set up this story didn't stick around to see it to its end, but the arc of WoW was eventually finished.
Warcraft is a franchise zombie at this point. The artists are gone. The IP is only head up as a skinsuit by corporate suits trying to milk as much money as possible out of the brand's name recognition and the religious fans who still cling to the product. Spiderman too started out with a clear goal in mind.
By issue 59, Spidey was no longer the boy he had started the story as. He was a respected man with a job and well on the way to marrying and starting a family. The story was almost over. But Spiderman had also become a successful IP for a corporation that was beginning to stagnate and needed to hang on to past glories to stay afloat, so they butchered Peter and kept his story going. And now nobody cares about Spiderman comics. Same with Batman: his destiny is to be punching a clown forever, not because that's a good story, but because it makes the suits money. Star Wars' story ended at episode 6 and anything after is superfluous. And so on.
I can go into detail about what I'd like new writers to do with Warcraft, but at the end of the day Warcraft has outstayed its welcome. Blizzard needs to move on to telling new stories. I was hoping Overwatch would have been a positive sign for Blizzard, but alas, by 2017 - a mere three years after it's announcement - it became clear that Blizzard had no idea what they were doing.

For a long time, the stance of Blizzard's developers (or the oldguard, at least) was that instead of making remakes of old games, they would rather use that time and resources to make a brand new game. That thought rings more true today than when it was made a decade ago.
Any reboot of WoW isn't going to be satisfying. It's not going to be made by the OG artists who created the thing that made people fall in love with Warcraft in the first place. It's going to be made by people who don't care about the source material who are servants of a corporate bureaucracy. It would be just as anti-Warcraft as modern Star Wars is anti-SW, or any other reboot.

I think the overabundance of character dialogue and cutscenes (both shoddy in engine cutscenes and tons of prerendered cutscenes) is a symptom of another problem that plagues modern WoW. It has turned into a soap opera. It used to be that you would only get CGI trailer and some ingame voice dialogue to contextualize why you were here in this war. The characters weren't really important. When we did get a prerendered cutscene, it was almost always to depict either 1. a monumental lore event (ie, Bolvar becoming the Lich King), or 2. an event that could not be depicted in the engine (ie, Deathwing smashing an airship). The game was about you going on adventures through high fantasy environments.
Now the game is about the writer's characters and their feelings. We get 5 minute long cutscenes dedicated to... characters standing around and talking, with closeups of their faces. As if we're watching some modern soap opera. I don't know who that appeal to. That's not what the Warcraft audience wants. JRPG fans might have their curiosity piqued but they're not going to last more than an hour in WoW.
