CoreJJ

Jo 'CoreJJ' Yong-in is the most decorated import player in North American League of Legends history, a Worlds 2017 champion who brought his elite Korean support play to Team Liquid and immediately elevated the organization into a perennial LCS championship contender. His journey is uniquely compelling — CoreJJ originally competed as an ADC before role-swapping to support on Samsung Galaxy, a transition that unlocked his true potential and culminated in a World Championship victory that proved he had found his ideal position. On Team Liquid, CoreJJ's impact extended far beyond his individual play: he became a vocal leader, a mentor to younger players, and the primary shotcaller whose in-game communication and vision control transformed Liquid's macro play from competent to championship-caliber. His Thresh play became his signature — CoreJJ's hooks, lanterns, and engage timing on the Chain Warden were consistently rated among the best in the world, regardless of region. Multiple LCS championships confirmed that his Korean pedigree translated fully to the North American environment, and his consistent All-Pro selections reflected the respect of coaches, analysts, and fellow players alike. CoreJJ's commitment to improving North American League of Legends extended beyond his own performance — he was known for hosting in-house games, coaching amateur players, and advocating for better competitive infrastructure in the region.
