Yes, you've heard it right! League of Legends and TFT are no longer published by Garena, starting January 2023.
The transition will begin on November 18th, 2022, and players are encouraged to log in on the Garena League PC Client to migrate before January next year. The new client and the blackout period will also launch in early January.
If you want to know how the migration goes, check the link here.
