There are several Domination Sites on the map that can be seized and contested by players. You can contest the Site by engaging in battle with the Crew representing the player who had seized the Domination Site before.
You can challenge your luck and try seizing any Site at any moment in time.
What is a Shuffle?
The Shuffle involves changing the Domination Site defending player and their Crew. The player who currently owns the Site does not lose because of the Shuffle, while the change has you surrounded by players more or less equal to you in their power and chances of winning the battle. That is how we ensure that no single power-player holds one given Domination Site forever.
The Shuffle takes place once in every 12 hours (at 9 AM and 9 PM UTC).
