Hello there, i had understood that there would be a free boost at the beginning of pre patch for TBC mine hasnt come yet though i can buy one.
Is there something ive missunderstood is the boost not free or will it come when the expansion is out thanks in advance 
From what I understand itâs a limit of 1 boost per account, not 1 free boost per account. You were always meant to pay for the boost.
I have never played WoW Classic but Iâm interested in Burning Crusade Classic. How can I join my friends?
If you donât have characters ready for the journey beyond the Dark Portal and are interested in adventuring in Outland with your friends, we will offer an optional Level-58 Character Boost service closer to the launch of Burning Crusade Classic.This boost will not be usable on Classic Era realms or on the new blood elf or draenei races; in addition, players will be limited to boosting only one character per World of Warcraft account. Further details, including details around pricing and availability, will be announced at a later date.
Ohh i see i just thought it was free :-/
