Riot recently announced that when the League of Legends Patch 1.73 drops sometime in mid-December (the 11th at the earliest), they’ll also be clearing out summoner names on low-level accounts that have not been played since January 1st, 2012. Any account below level 6 that hasn’t been played this year will have the summoner name associated with that account cleared and made available to the public. These accounts will not be deleted, but a new summoner name will have to be chosen if the account is logged into at a later time.
Along with this summoner name cleanup comes a sale on summoner name changes that will run from the release date of Patch 1.73 through December 26. Summoners will be able to pick up a name change for 650 RP, down from the usual 1300 RP cost. If you’re buying RP specifically for a name change, you can get the required RP for $5.
