Yes, I think it has too many followers right now. Perhaps it returns to 'normal' after the hype wears off. It has happened before just not to this scale.
Subreddits never return to normal after mass subscriber events. The users might not contribute, but so long as a fraction remain active on the same account, WSB posts will stay in their feed, and they will have the power to vote, and therefore dictate the content of the sub. The participating community will always be a minority, and will inevitably grow to disagree with the majority of users, nonparticipants, who simply dictate the content of the sub because of their higher voting power. The number of votes on a post always exceeds the number of unique posters in the post. I've seen it ruin several subreddits already, with easy-to-consume, low effort content swamping the frontpage.
