Yongin Jo, universally known as CoreJJ, is one of the most decorated and respected support players in League of Legends history. A South Korean veteran now 32 years old, he anchors the backline for Team Liquid Alienware in the LCS, where his voice, vision, and shot-calling carry the weight of a career spanning two continents and multiple eras of the game. Few players in the support role command the reverence that CoreJJ does.
CoreJJ’s reputation was forged at the highest level of competition, and his transition from Korea to North America transformed him into a cornerstone of the LCS. Supports are often the unsung architects of victory, orchestrating vision control, engaging fights at precise moments, and shielding their carries through the chaos of team fights. CoreJJ embodies this ideal, blending immaculate macro understanding with the leadership that turns a collection of players into a cohesive unit.
His champion identity leans into playmaking, and Zyra exemplifies the aggressive, zone-controlling flavor he can bring to the lane. As a mage-support, Zyra punishes overextensions with layered damage and turns skirmishes into deathtraps, rewarding a player with the timing and positioning to maximize her plant-based pressure. It is a pick that suits a support who wants to shape fights rather than merely react to them.
Beyond mechanics, CoreJJ is valued for the intangible qualities that define elite supports: communication, composure, and the ability to elevate teammates. Playing for Team Liquid Alienware, he serves as both a stabilizing force and a strategic compass, guiding drafts and in-game decisions with the authority of a player who has seen nearly every situation the game can produce.
At 32, CoreJJ occupies rare air in a scene that tends to favor youth. His continued presence in the LCS is a testament to his professionalism and his enduring passion for competition. However his current campaign unfolds, his legacy as one of the definitive supports of his generation is already secure, and every match he plays adds another chapter to a storied career that younger players will study for years to come.
