Actually yes, the two brothers were ingame friends, pro raiders back then and they started new characters right before the tbc pre release. They wanted a new start with TBC.
I remember this because I simply couldn’t believe they would achieve this. Sure, they were prepared, they certainly didn’t have to organize anything during leveling. When I logged in on day 7 I was greeted by level 60 chars.
I could never have done that. That’s for sure
