Pacific Championship Series

Origins and Formation

The Pacific Championship Series was born from a consolidation of existing regional competitions. Prior to its creation, the primary league for the area was the Garena Premier League (GPL), which ran from 2012 to mid-2018. In late 2014, teams from Taiwan, Hong Kong, and Macau were given their own dedicated league, the League of Legends Master Series (LMS). Vietnam later became its own separate competitive region in 2017 with the Vietnam Championship Series (VCS), and the GPL was rebranded as the League of Legends SEA Tour (LST).

On 25 September 2019, the game's distributor Garena announced plans to merge the LMS and LST into a single league. Riot Games officially revealed the new league's name, the Pacific Championship Series, on 19 December 2019, along with a list of nine of the ten founding teams. The final team, Berjaya Dragons, was confirmed on 17 January 2020. Riot Games stated the league was intended to increase competition across Southeast Asia, Taiwan, and Hong Kong and create a more engaging fan experience.

A Turbulent Inaugural Season

The PCS began its life amid global uncertainty. Its first season in 2020 was postponed on 29 January due to the COVID-19 outbreak. A start date of 29 February was later confirmed on 18 February. Before the season could begin, the league faced its first roster change. On 13 February, G-Rex disbanded its team and forfeited its spot due to internal restructuring by its parent company. Machi Esports was announced as the replacement team five days later.

The league started with ten teams selected as permanent franchise partners. However, this structure was not set in stone. By 4 August 2020, Riot Games announced a promotion tournament would be introduced for the 2021 season to promote regional competitiveness, indicating a move away from a fully closed partnership system.

Structural Changes and Regional Shifts

The league's team count and format were not static. It began with ten teams, but this number was reduced to eight for the 2024 spring season and finally to seven for the 2024 summer season. The competitive format also evolved, especially regarding its relationship with neighboring regions.

In its final year as a tier-one competition, the playoff format reflected its expanded reach. The top six teams from the PCS regular season advanced to the playoffs and were joined by the top three teams from Japan and the top two teams from Oceania. This was the result of a phased integration that fundamentally changed the league's scope.

Expansion to Oceania and Japan

A major chapter in the PCS story was its expansion to include teams from other Asia-Pacific regions. On 18 November 2022, Riot Games announced that Oceania would become part of the PCS region starting in 2023. The League of Legends Circuit Oceania (LCO) was downgraded to a tier-two league secondary to the PCS. The winners of the LCO would no longer directly qualify for the Mid-Season Invitational or the World Championship. Instead, the LCO's top two teams had to compete in the PCS playoffs to gain a spot. Player residency rules were also changed, with LCO players becoming PCS residents, meaning they no longer counted as imports on PCS teams.

This model was extended to Japan on 26 November 2023. From 2024 onwards, the League of Legends Japan League (LJL) was similarly downgraded and integrated. The top three LJL teams had to compete in the PCS playoffs for a spot at international events. LJL players also had their residencies changed from Japan to PCS.

The Transition to a Tier-Two League

A fundamental shift was announced in 2024. Riot Games revealed that a new top-tier league, the League of Legends Championship Pacific (LCP), would launch in 2025 as one of five premier global leagues, replacing the PCS at the top of the Asia-Pacific hierarchy.

In this new ecosystem, the PCS was repositioned as a domestic league for Taiwan, Hong Kong, and Macau, a role similar to its predecessor, the LMS. It became a tier-two league alongside the LJL and the Vietnam Championship Series (VCS), all serving as pathways to promotion into the LCP. The LCO was also confirmed as a tier-two league in this structure. Additionally, a separate wildcard tournament was created for Southeast Asian teams, excluding Vietnam, offering another qualification route to the LCP.

Teams and the New Ecosystem

After the league's demotion to tier-two status in 2025, a new team dynamic emerged. Partner teams from the top-tier LCP began fielding academy squads in the PCS. These academy teams, however, are not eligible for promotion to the LCP or relegation to lower-tier regional leagues.

Looking ahead, the league's record-keeping format was refined. Starting from the 2026 season, only teams that qualify for the main tournament's knockout stage in either the Spring or Summer split will be included in official records and standings. This marked another step in defining the league's identity as a competitive proving ground.

Historical Context and Legacy

The PCS represented a specific era in League of Legends esports for its region. It was born from the merger of two leagues, the LMS and LST, which themselves had evolved from the earlier Garena Premier League. For several years, it acted as the primary competitive stage for a combined region that grew to include Oceania and Japan for playoff purposes.

The series first brought together scattered competitions under one banner to strengthen the region, before ultimately being restructured to feed a new, higher-tier league. The PCS continues as a crucial developmental league, maintaining the competitive pipeline for its core territories of Taiwan, Hong Kong, and Macau.
