Honestly, i'm done with current WoW and their expansion model, there is little to nothing they can do to bring me back to WoW. In my opinion this game has reached a point where a sequel makes sense for a variety of reasons. Mostly old systems and concepts that are at the core of how the game works that feel like something that made sense 20 years ago for an MMORPG, but that has been vastly improved or reimagined by several games over the years, just as the online gaming scene changed too.
And by this i don't mean to say that the game doesn't work because it's old (it was already old in legion and i loved it), but i wonder if new developers feel somehow limited by those old core systems. I have to wonder if current developers would choose the same class/spec system, the same type of combat system or even how they build the world and how we interact with it in the same way. Similar to that, i have to wonder if lore, as bad as it is right now, could benefit from a time jump that allows them to create new stories, new characters and new lore with more foundation than just being the next big world ending threat that came out of nowhere and we just met.
But i am fully aware that this will never happen. They can still milk wow with their current model for a lot of years, this includes releasing classic servers for more expansions. This is still an almost 20 year old behemoth and when the inevitable demise comes and is no longer profitable, they'll just stop developing new content, keep some servers up and let people slowly forget about it.
