Riot Games is back from A Week Off and implemented some balance changes in League of Legends with Patch 10.16b now live on servers.
Basically all you need to know is that we are going from Patch 10.16 > 10.18, and 10.18 will hit live whenever your region is on 02 September. 10.19 will hit PBE on 01 September (LA time).
