Players will be required to play under the name that they wish to use during the WCS Circuit summer Championship. A free character name change was provided to every account on June 20th. Player’s account names have to be recognizable (no ‘bar code’ or otherwise unknown alias) once Grandmaster League opens. Any later name changes will render that account ineligible for the respective top 16 final.
