Ruler (Park Jae-hyuk) — LoL Professional Player Settings and Gear
About Ruler
Park 'Ruler' Jae-hyuk is the ADC whose Worlds 2017 championship-winning play — a perfectly timed Xayah ultimate and feather recall that turned a lost teamfight into a pentakill sequence in the Grand Finals against SK Telecom T1 — produced one of the most iconic moments in League of Legends history. That single play encapsulated everything that made Ruler special: mechanical precision under extreme pressure, perfect cooldown awareness, and the composure to execute when the entire world was watching. His career on Samsung Galaxy (later Gen.G) spanned nearly a decade of elite-level competition in the LCK, making him one of the longest-tenured and most respected ADC players in Korean League of Legends history. Ruler's playing style combined the aggressive laning of a carry-oriented ADC with the late-game positioning and teamfight execution of a more conservative player, a duality that made him effective across every meta shift the game underwent during his career. His consistency was remarkable — Ruler maintained a top-tier level of performance across multiple coaching staffs, support partners, and tactical systems, suggesting that his impact came from fundamental excellence rather than circumstantial synergy. The Worlds 2017 championship victory with Samsung Galaxy against the Faker-led SKT roster remains one of the greatest upset stories in Worlds history, and Ruler's Finals MVP-caliber performance was the primary reason it happened.
