its not like a SE executive sit on a pc looked all of the applied accounts for Alpha and started picking them up by himself so just deal with it more or less dont forget that its just 1 server (is it or is it not) and if half of it are JP quite imagine how to deal with many active players who submitted the application for alpha from around the world also think the server would handle it smoothly i doubt it tbh.
in the end if u didnt get in alpha theres another chance for a beta and if no beta you can just wait for the release.
