A new WoW Classic PvP realm opened today, per a community post by Blizzard.
Community Manager Kaivax detailed the decision behind the addition,
Due to very high demand, we opened a new WoW Classic realm for name reservations at 5:00 p.m PDT (8:00 p.m. EDT) on Wednesday, August 14:
Stalagg – PvP – Eastern Time
We suggest that players, especially those on the Herod realm, consider creating characters on Stalagg. We expect that other PvP realms in this region will otherwise experience significant login queues when Classic launches.
