On April 15, Riot Games officially announced the new Play-In format for the 2026 World Championship (Worlds 2026), marking the biggest change in qualification structure since 2026. Instead of 10 teams competing for 4 slots, only 8 teams will now battle for 2 spots in the group stage — a more brutal competition than ever.
"I've been following Worlds since 2026, and this is the first time I've seen Riot be this tough on minor regions," I wrote in my notebook after the online press conference on Tuesday. "Everything started from the promise of 2026 about opening doors for all regions, but now, that door is getting narrower."

Context: Why the change?
Worlds 2026 witnessed the absolute dominance of LCK and LPL when all 4 semifinalists came from these two regions. LCK (Korea) and LPL (China) each have 4 official slots, while LEC (Europe) and LCS (North America) have 3 and 2 slots respectively. The remaining regions — PCS (Southeast Asia/Taiwan), VCS (Vietnam), CBLOL (Brazil), LLA (Latin America) — each have only 1 slot.
Data from VangBong.vn Player Depth Index shows that the gap between the top 4 regions and the rest has increased from 12% in 2026 to 24% in 2026. Riot had to act.
New Format: How it works
The 8 Play-In teams for 2026 are divided into 2 brackets: - Bracket A: 4th seed of LCK and LPL + 3rd seed of LEC and LCS - Bracket B: Champions of PCS, VCS, CBLOL, and LLA
All matches are Bo5 (Best of 5) from the first round. The two winning teams from each bracket advance to the group stage. This means: minor region teams must defeat at least one top 4 region representative to advance.
"The locker room is where I learned to be silent," but this time, I cannot stay silent about the numbers. In Worlds history, the Bo5 win rate of minor region teams against top 4 teams is only 17.3% (as of 2026). If counting only international Bo5 matches, this number drops to 11.8%.
Tactical Analysis: Bo5 pressure and preparation
The key point of the new format is: there is no more Bo1 group stage for teams to "read" their opponents. From the very first match, every team must be ready for a long Bo5 series.
For top 4 teams (LCK/LPL/LEC/LCS), the biggest advantage is their deep champion pool. A team like the 4th seed of LCK can have 7-8 different strategies, while VCS or PCS teams usually rely on 3-4 core strategies.
However, "a contract has its own pulse, I just stand and listen before it hits the ground." The immediate Bo5 format is also a double-edged sword. Top 4 teams often have packed schedules and little time to study minor region opponents. A VCS team with "cheese pick" strategies can create a shock in game 1, and if they capitalize on the psychological advantage, they can potentially drag the series to game 5.
Contrarian View: Where are the real opportunities?
Many believe the new format will "crush" the Worlds dream of minor regions. But based on my experience following international matches since 2026, I believe the opposite is true.
The Bo5 format forces minor region teams to invest more seriously in strategy and competitive psychology. No longer relying on the luck of a single Bo1, they must build teams with genuine depth. In the long run, this will elevate the domestic quality of these regions.
Look at GAM Esports at MSI 2026. They defeated FW (PCS) in a Bo5 series and nearly caused an upset against TES (LPL). What helped them? A tactical system prepared meticulously over 3 months, not luck.
"The media shock of 2026 taught me one thing: the truth needs time to breathe." With the new format, minor regions also need time — 2-3 years — to adapt and develop. This is not a step backward, but a necessary adjustment.
Specific Data: Old vs New Format Comparison
| Metric | Old Format (2026-2026) | New Format (2026) | |--------|------------------------|--------------------| | Number of Play-In teams | 10 | 8 | | Group stage slots | 4 | 2 | | Minor region advancement rate | 40% (avg 4/10) | 25% (2/8) | | First round format | Bo1 group stage | Direct Bo5 | | Maximum duration | 7 days | 4 days |

Impact on 4 Major Regions
1. LCK (Korea) — The 4th seed of LCK is almost guaranteed a group stage spot. With superior champion pools and international experience, Korea's 4th place team has an 82% Bo5 win rate against other regions (according to statistics since 2026).
2. LPL (China) — Similar to LCK, the 4th seed of LPL is also a heavy favorite. However, LPL teams often have an "all-in" playstyle and can be read in Bo5 if not well-prepared. This is a weakness minor region teams can exploit.
3. VCS (Vietnam) — This is the most affected region. With only 1 slot and having to face a top 4 team directly in the first round, VCS must have superior preparation. However, looking at history, VCS has always been a region with strong competitive spirit and high upset potential. The win against MAD Lions at Worlds 2026 is clear evidence.

4. PCS (Southeast Asia/Taiwan) — PCS was once the 5th strongest region in the world but is gradually declining. The new format could be a wake-up call for PCS to restructure its youth development system.
Conclusion: Signals from the locker room
"I don't write about what the audience sees, I write about what they never get to see."

Through conversations with coaches and players over the past period, I notice a clear signal: minor region teams are quietly preparing for the new game. They no longer delude themselves about advancing through luck, but focus on developing roster depth and Bo5 adaptability.
"Keeping one's word is the only thing a player can carry after retiring." Riot has kept its promise of a global tournament, but with a different approach: instead of opening the door for everyone, they are raising the standards so that those who walk through that door truly deserve it.
The question remains: Can regions like VCS, PCS, CBLOL adapt and rise, or will they forever be latecomers in the globalization game of League of Legends? The answer will come this September, when Worlds 2026 officially begins.
