Participants must keep a majority of players that match the criteria of the qualifier from which they qualified for the event. For example, a participant who competes in and wins a Germany qualifier must keep a majority of German players for the event. Similarly, a participant that competes in a Europe qualifier must keep a majority of players residing within Europe.

For participants who are invited to an event, they must retain a majority of players that match the criteria for which the team was invited. For example, a participant invited in the ESL World Ranking South America slot must keep a majority of players who reside within South America. For teams invited in a Local Hero slot, they must keep a majority of players who reside within the host country or region.

Participants who have received a special exception to compete in another region's qualifiers, or who have moved regions in the time since qualifying for or being invited to an event, are not held to this standard but they must still keep a majority of the players they used to qualify or that were a part of the invited line-up.
