Yes i do know whar im talking about. Blizzard themselves said they expect severe queues when layering is pulled.
Based on name reservations so far, the Herod realm is looking to be massively overpopulated. If all existing players on this server remain there, login queues in excess of 10,000 players are a certainty, and possibly much higher than that. We recently opened up the Stalagg realm, and we urge players on Herod to consider moving there. There are a lot of players currently on Herod and we want Stalagg to fill up before we open any new PvP realms. This is so that player population is spread as even…
If you want to argue contrary to blizzard you are going to have to provide a legit source from them saying mega servers would happen.
