It's the general consensus (and I agree) that Cata was the start of the decline of WoW, gameplay and lore-wise.
With the success of Classic through WotLK, Blizzard is presented with an opportunity that no other company has ever had: fix the lore, retcons and design mistakes.
My idea is simple: Blizzard creates a compelling and convincing lore (I'm asking too much, I know) that explains a timeline split that happened in Cata. In one timeline we have Cata, MoP, WoD and etc. and in the other we have a fresh path to an unknown future, maybe plugging in the best features of each expansion or even entire xpacs (like Legion).
Is it feasible? I know that, technically, it is. I also know that whatever Blizzard do, the playerbase will gobble-up. So, the only question is if it's feasible from a political/player engagement perspective.
What y'all think?
