Seems like you misunderstood this part too.
The “emotional investment” and “glue” I was referring to, doesn’t have anything to do with playing on the server per se.
It’s about playing or not playing, period.
It’s easier for a player to just up and leave a private realm than it is to leave classic altogether, on a subconscious level. Due to the investment placed in classic, both financially and emotionally, instead of just emotionally.
So the reputation is everything for a private server population, while in classic it gets thrown around more because people don’t give up permanently as easily.
Which is why private servers just died, while in classic the player base will move from server to server after enough time has passed. Classic is still in its diapers, sociologically speaking.
Give it at least a year. Right now you’re just seeing the effects of the tourists leaving, because they can’t handle punitive game design.
Also, the effects of phase releases will also affect the server populations greatly, so you’ll see different realm populations after phase 6 has been out for a year, compared to now when they release phases with just a few months inbetween.
