Overview
We’re going to give you a quick rundown of key points from the latest patch. You can also see how these changes have affected the meta by looking at our Champion Statistics page, which highlights changes in Win Rate between patches.
The first major patch for Season 2 introduces a sweeping update to AP items, but the biggest new thing to look forward to may be the new game mode, Brawl, which you can read more about here. Brawl will be live at 8:00 AM Pacific time on May 14th and will be around until patch 25.13 goes live on June 24th.
