A WoW Forever guide. Check the stated version and date: mechanics may change during development.
One choice reaches all your characters
Blizzard’s October 22 overview of official Forever describes as an account-wide setting. It applies to every character, and changing it starts a 24-hour wait before another change. Choosing a different character therefore does not give that character an independent under this description.
Before touching the setting, agree which language your regular will use for short instructions and questions. Think about the other characters you play as well. A choice made for one evening may still be in force when you return for another activity, because the next change cannot happen immediately.
Check the setting on the account you will use
The path given by Blizzard is , then , , , and finally . These are the English menu names from the source. Use the described setting as your reference rather than assuming that a separate language control elsewhere changes the same preference.
If you change it, note the time before arranging another session that would require a different choice. Avoid asking everyone to toggle repeatedly while discussing what to use. It is easier to settle the communication language first, then have each player inspect the setting on the account they actually intend to play.
The setting does not replace shared instructions
A is not a promise that every line of client text will be translated or that a particular friend will be placed with you. Keep the practical agreement separate: decide how to ask for a pause, announce movement and confirm that everybody understood. A short, familiar phrase is often easier to follow during a busy moment.
