Sorry but how is Classic a massive indicator that people who dislike the modern direction of WoW isn't some insigificant minority when the entire classic playerbase is now 2-300k people and probably at best 1/5 and at worst 1/10th of the current retail playerbase?
Classic brought a lot of people back to WoW but the reality is only a fraction of the classic players are still actually there.
If anything classic shows that the playerbase doesn't want recycled shit they want new content (seeing as Shadowlands was the fastest selling PC game of all time - ok for a week but it still sold more initial copies than any other expansion).
