After announcing pre-registrations for WoW Classic players, some of Blizzard's servers are facing queues of more than 10,000 people.
The option to reserve character names was made available this week, giving players the ability to choose which realm (server) they'll be playing on.
Community manager Kaivax has advised that some players may want to consider choosing another server ahead of the game's release on August 27.
"Based on name reservations so far, the Herod realm is looking to be massively overpopulated," wrote Kaivax of the US server. "We recently opened up the Stalagg realm, and we urge players on Herod to consider moving there."
Another server facing overpopulation is Europe's Shazzrah Realm, where Kaivax is again recommending alternative servers.
"While we are able to fit several times more players on a single realm in 2019 than was the case in 2006, we are not going to raise that cap any further, even though we have the technical capacity to do so," Kaivax explained.
"Raising realm caps would simply forestall the problem, letting more players in at launch but creating an unsustainable situation down the line, with severe queues when we turn off layering permanently before Phase 2 of our content unlock plan."
Whether the popularity of WoW's classic servers is going to be long-lived is yet to be seen – but for this reformed player, the urge to jump back into the plains for Mulgore and kill some boars is very very real.
