On February 29, 2012 starting at 11:30pm Pacific Time ranked queues will be disabled in preparation for the patch. At 1:00am Pacific Time, the servers will be shut down and Fiora, the Grand Duelist, will begin her journey to the League. At this time all games currently in progress will end in a draw and stats will not be recorded. We estimate that the battlegrounds will be unavailable for approximately 6 hours.
Once the update has been completed, all game balance changes will immediately become available and Fiora and her skins will become available in the League of Legends Store.
