With the IEM Cologne Major 2026 in the books, ESL's biggest structural bet on the tournament — making every Stage 3 match best-of-three — received near-universal praise from players, coaches, and analysts.
What Changed
Previously, Major Swiss stages used best-of-one matches. This produced upsets, but critics argued that too much variance made the Swiss stage feel more like a random-outcome exercise than genuine skill evaluation. The all-BO3 Stage 3 replaced that with a format where every match was a proper series.
Player Reactions
- Multiple pros praised the change as reducing "one-map coin flip" outcomes
- Coaches noted better opportunity for tactical adjustments mid-series
- Fans got more high-quality Counter-Strike per matchday
Broadcast Value
The 100 million total hours watched — a first in CS history — vindicated the format decision. More matches meant more broadcast inventory, more sponsor opportunities, and more content for viewers.
The Downside
- Longer tournament schedule (Stage 3 required five days instead of a possible three)
- More physical demand on players competing across five straight days of BO3s
- Broadcast fatigue for viewers on later days
Verdict
The consensus verdict is: the change is here to stay. Future Majors will likely follow the same format, potentially even extending BO3 to Stage 2 in future iterations.
What's Next Format-Wise
- Stage 1 remains BO1 for the opening round, BO3 for elimination and qualification
- Stage 2 in the same format
- Stage 3 will remain all-BO3
- Playoffs remain single-elimination BO3s with a BO5 grand final
ESL and Valve's Approach
The format changes suggest a growing willingness to evolve Major structure based on community and pro feedback. This iterative approach to Major design is what fans have been asking for since the CS2 transition.
