This is waaaaaaay too average and over hyped like holy crap but it does what it's supposed to do I guess. A couple of these things definitely don't work on 1.7.10. You should make arguments for players in a few of these commands where possible. You should also use list variables.

This is only 3 commands but they do what they need to do. Also, would recommend adding your options at the top of the code so the user can edit them easier and replace the other prefix's with the {@Prefix}:)

I do not totally agree with "your server will not survive without it" but it seems good for its purpose.
