Regarding player-versus-player combat, Classic Hardcore will shift the focus away from it to a certain extent. Queueing for battlegrounds, for example, won’t be possible. However, Blizzard will introduce a new dueling mechanic that allows players to challenge each other to a fight to the death. Emerging victorious in such a duel will grant a permanent cosmetic buff called “String of Ears,” which keeps track of the number of players you have successfully defeated.
The arrival of hardcore servers in World of Warcraft Classic is slated for before the end of summer. Prior to that, a public test build of the new mode will be available for players to experience starting from June 29th.
