What is the Server Change Restriction?
It is a system that restricts server changes for a certain period.
Server changes are not possible during the restriction period.

Reason for Restriction
This is a policy to maintain game balance and prevent server abuse.
It is operated to ensure a fair gaming environment.

How to Lift the Restriction
The restriction period is automatically lifted after 7 days from the server change, and arbitrary shortening of the period or server changes are not supported.

Recommendation
Selecting a server that matches your residential region will lower your ping.
