A RuneScape world switcher, much like SwiftSwitch. Eliteswitch totally took swiftswitch's idea. Eliteswitch is also illegal to use on RuneScape because it has autoing programs on it as well as the ability to switch worlds easily.
An Eliteist is one who discriminates or has no respect for anyone who is better or worse than themselves.
To an eliteist somone who is higher level, more skilled, etc is a nerd who has no life where a less skilled or lower level player is a horrible player who can never be as good as the eliteist him/herself.
