From the WoW dev who said 60% of their current subscriber base is Chinese. Though I could be butchering that quote. It’s not high in NA and hasn’t been for years.
It’s floating around in different places but you have to dig for it. Look for the interview with the dev who said the playerbase is mainly Chinese.
Actually I was wrong, the quote was 70%. See: Retail Playerbase is 70% Chinese According to Blizzard Employee
Most don’t complain on the forums. They just leave.
Participation metrics are a horrible way to gauge player interest. A better way is to just ask the players if they enjoy it. It’s not difficult!
And as I said, the worst possible outcome is they don’t have the money to sustain development on lore and Art (both of which I gladly pay for) because the game isn’t worth the price of admission. If I stop paying for it that just puts more pressure on the publisher to let people go which TBH, isn’t going to help the game.
What genres have branched out? Be specific. Are you claiming that BRs are an evolution of MMORPG or something like that?
