MTE. Honestly, I'm a little surprised SE has yet to do this, given the severity of the issues they've been dealing with. They're aware that they have a congestion issue, but instead of implementing some method for lightening server load, they restrict character creation. This is a new game and there are people wanting to create characters on servers of their choice, and that option's been taken away because of server congestion and other issues, when there're players clogging the worlds who don't even play but log in simply to go AFK for several hours.
