Is there a way to disable the achievement toast? That shit keeps poping up during raid when people complete guild challenges.
He's refering to guild challenges, but complaining about achievements.. And achievement announcemets CANNOT be disabled, according to a blue post I cba digging up...
Guild achievement announcements in chat are a chat category in the chat options that you can untick.
You can AlertFrame:UnregisterEvent() for ACHIEVEMENT_EARNED, GUILD_CHALLENGE_COMPLETED and a number of others.
