I have no idea why you think players would be capable of self-regulating, we’re not all coordinating with each other. We’re all in it for ourselves, that’s why when overpopulated servers get free xfers the vast majority don’t want to leave to a low pop realm that people just kind of sort of hope gets a decent population because they hope other people will fix the problem for them and if they see a high populated realm they’re willing to xfer there and abandon their dead realm which makes it even more dead.
Not only that but $25 to fix your playing issues is not the end of the world for most people, especially those already forking over $15 a month.
