How to change layers in WoW Forever? (After the layer size change)

WoW: Forever uses layers and sharding to manage player numbers, but these systems can make it harder for friends and guildmates to meet in the same game instance. The article explains how these copies of areas or of the whole world work, and why moving between them can affect play.

Shards copy individual zones, while layers copy Azeroth as a whole; both help limit crowding, lag and shortages of quest resources. Players report that Forever appears to retain Retail-style sharding, with possible automatic layer changes during zone transitions, which can make characters phase in or out and interrupt PvP. Blizzard’s precise system for Forever was not confirmed in the article, and layering can also affect cities and resource gathering.
