Ohhh i dunno...
maybe if u live in the east u pick east and west is west u big derp

east coast has all the eastern people
western has all the western people

if u live in east , play east
if u live in west , play west

There really is no difference. Just choose whichever server you don't lag as much on. Although if you wind up playing on East, you can go ahead and add my character, Filorial.
