The following adjustments have been made to the ready check feature.
  • Players can no longer use the ready check feature if they have generated any enmity on a monster. If a party member who has yet to generate any enmity initiates a ready check, the ready check confirmation answer for players that have generated enmity against a monster will automatically be submitted as “No.”
  • A “Respond Later” option has been added. When this option is selected, the player can place a temporary hold on answering the ready check confirmation. To submit an answer after selecting to respond later, select “Ready Check” from the social menu to re-open the ready check confirmation dialogue box. If the player is still using the “Respond Later” status after the 30-second confirmation period elapses, that player’s answer will be automatically submitted as “No.”
  • The name of the player who initiated the ready check will now be displayed on-screen and in the chat logs.
  • The results window will no longer automatically reappear after a player has selected a ready status.
