Most interesting roles that aren't too bugged or over-powered as of 13/7/12.
In other words no boring roles like miller/paranoid cop/mortition/framer/quack, no bugged roles like godfather/warlock and op roles such as zombie/poisoner are also not included.
Also OCD compatible, has perfect boxes.
*EDIT* No longer OCD compatible after the site look edit, new version is http://www.epicmafia.com/setup/634441
