I’ve heard quite a few people unhappy that the new achievement system spams their guildchat relentlessly, even when they’ve turned off global achievement announcements.
Here’s how to disable them:
For nearby/chat announcements
- Right click on the tab of your chat window
- Go to “Settings”
- In the left-hand column, pick “Other”
- In the right-hand area, look for an option for ‘Achievement Announce’; uncheck it
For guild announcements (as discovered by my guildmate Wildence, after a bit of adept Googlefu)
- Right click on the tab of your chat window
- Go to “Settings”
- In the left-hand column, pick “Chat”
- In the right-hand area, look for an option for ‘Guild Announce’; uncheck it
Enjoy!
