In one of the biggest changes League of Legends has seen this decade, Riot Games is reducing item power levels by as much as “five to fifteen percent” across the board in a huge preseason patch in a bid to make champion choices actually matter again.

The overhaul, which has been dubbed the “Champion Emphasis” update, is expected to hit as many as 119 Legendary League items and herald changes for every single class in the game, ranging from skirmishers and tanks to AD carries and assassins. The aim, the Riot balance team explained in a September blog, is to “put more emphasis on champions” again after various changes and improving player skills shifted things the wrong way.
