Greetings reader!
To be short, anyone without the BfA extension on his account, whether or not with gametime, meet the error “Join as group failed” when trying to join the Korrak’s Revenge (aka, the “new” old Alterac Valley Battleground bringed back for the anniversary). Over the two GMs to who I spoke about it, none was aware of such restriction, which is why I bring this issue here.
The battleground was advertised to phase everyone (from the young lvl10 to the experienced lvl120) to level 60 and also to be a great way to level up during the event, and nothing was said about a potential restriction over the purchase of BfA … because after all, even if you didn’t play during BfA but were a regular for all the previous years, you should be able to celebrate WoW’s anniversary
(i’m not talking about timewalking stuff which requires obviously max-level character and thus BfA)
