Blizzard is warning for queues on several WoW Classic realms in excess over 10.000 players upon the launch of the vanilla server option for World of Warcraft later this month.

Last week, we already covered that Blizzard is expecting severe queues due to extremely high demand after Blizzard kicked off name reservations on the upcoming Classic realms. The WoW Classic team is now warning fans that various realms will be massively overpopulated and urges players to move to other realms. According to Blizzard, they already raised the player cap on Classic’s servers.
