This article examines the significance of two types of expertise in the popular multiplayer video game League of Legends. Previous research into multiplayer games has explored a variety of expertise models, some which concern only a player’s mastery of the controls and some which take negotiation of a game’s sociocultural context into account. This article analyzes play in League of Legends through the lens of a binary model of expertise, outlining examples of the in-game and out-of-game practices used by players in their pursuit of competitive success. I argue that forms of out-of-game or "metagame" expertise are of particular importance in League of Legends and are of such depth that further research would be highly valuable.
