Post-TI Reset: How Roster Shuffles Break Dota 2 Team Ratings

Introduction — The Aegis Is Lifted, Then Everything Changes

The International or TI is not just the biggest Dota 2 event of the year, but it is also the most prestigious Esports event in the world based on its history and value. Dota 2 players prepare for a whole year just to reach this event and attempt to lift the aegis. Losing at The International, which is something all teams face except for the winner, extracts a heavy toll on players who have been consistent and putting in effort throughout a full year.

This leads to a massive roster change within almost all active Dota 2 S-Tier teams, and it has turned into somewhat a yearly tradition, so much that orgs time their player contracts to end by the end of TI.

With S-Tier Majors debuting right after TI, within a few weeks, this creates great uncertainty and majorly shifts the odds when it comes to teams’ and players’ reputations, as the veteran names might not retain their veteran players anymore, and some underdogs might just have the next best roster in Dota 2 history.

What Does a Team Rating Actually Measure?

Team Rating or Reputation is generally a good and reliable indicator on the potential outcome of any match and/or tournament before TI, it reflects the team’s history and advantage when it comes to the current meta and the coming tournament. The only exception to this rule is during and a couple of months after TI. 

Teams are ranked based on their performances in recent events generally, and some teams even gather reputation over the course of years. A clear example of both would be respectively Team Vision and Team Liquid. The latter, having won The International 2017 and 2024, did so with two completely different lineups, yet still carrying a high reputation throughout the years in contenders’ eyes even with roster changes, although most of the times this gets corrected throughout the course of the year. On the other hand, Team Vision started the season (right after TI) with a rough start, although having built around a strong combination of players, yet have built their reputation so well across the entire 2026 season all the way to TI, winning EWC 2026 and becoming the favorites for TI, which was accurate as they made it to the Grand Finals and lost 3-2 to Spirit who matched their performance exceptionally well. 

The primary thing to highlight here is that reputation and rating don’t always reflect the quality of the team or the performance, but mostly past achievements and old roster results.

Why One Player Can Change More Than 20% of a Team

Dota 2 is a 5-player game, and every player has a role to perform, whether it’s in-game, in the metagame, or even outside the game. That being said, when roster shuffles occur and we notice some teams only change one or two players, instead of a full shuffle, it is usually because said player(s) are not performing all their duties in said circumstances.

Communications and compatibility stretch far beyond the lane and the ancient. Teammates spend long periods together in bootcamp before events., eat together, plan together and discuss quite a lot. Anything that would disrupt a smooth flow of the mentioned examples above, would not only affect the individual player’s performance, but the whole team’s performance. I can dive deeper into the influence of a player’s role in-game on the whole team morale and momentum, but this needs a completely separate article.

This is why sometimes getting a superstar on a 4-man roster might not always be a good indicator that the team will be performing better. Cohesion and compatibility are always experimental and do not appear until really big events like TI and EWC.

The Adjustment Period: Talent vs. Cohesion

Having discussed the value of each player towards their team, and the influence that stretches far beyond just a fifth or 20%, it is important to highlight the “Adjustment Period”, known as the time it takes for a team to grow the synergy needed to help each individual talent perform at their best.

Successful teams throughout the years tend to have one of two major “winning” factors, and one of them is more often spotted than the other. You either have an exceptional roster of exceptional players who are all above the rest, like most Chinese teams who have won TI before, and even Team Falcons in 2025 and Team Liquid in 2017 also displayed Star Player efficiency and performance, but this is really shadowed by cohesion and compatibility, displayed primarily by OG in 2018-2019 winning back to back TI with the same roster, as well as Tundra and Spirit lifting each two Aegises 4 years apart.

Sometimes it takes more than one season, for a team to reach full synergy, most notably in teams like Falcons and Vision in the recent years, where their formation did not instantly spark a winner aura, but the synergy they built over the course of several months led to having two of the best performing teams Dota 2 has ever witnessed.

Reputation vs. Reality in Betting Markets

Perception of reality for the audience and bettors can always be altered by what we have discussed earlier in this text, whether it’s roster changes, former reputations, star player influence and much more. It is always important not simply to read the odds from afar, but to always make sure the water loses its murkiness after the pinnacle of the season. Rosters change, tournaments change, the meta changes, and a lot of variables come into play.

For what we have discussed thus far, it is important to highlight the importance of reputation in shifting the odds of the professional Dota 2 tournaments and matches. The only semi-conclusion we can take out so far, is that, just as mid-to-late season games can give us quite a clearer picture on the outcome of matches and tournaments based on team history and reputation. This is also why odds displayed on platforms such as Dexsport should be treated as a starting point rather than a final assessment of team strength. After TI, an organization's reputation may still reflect months of results achieved by a roster that no longer exists.

What Bettors Should Examine After a Shuffle

Let’s start simple, Dota 2 is a MOBA, and like all MOBAs, strategy and performance come as your first indicator of who is a better roster in general. But same organizations do not equal same team after TI, and better players do not immediately equal a better team.

However, if we were to dive a bit deeper and benefit from the uncertainty after post TI shuffle, instead of relying primarily on ranking, the following parameters should be taken into account:

• Roster continuity: If the same team kept its original roster, it means dedication and perseverance and seriousness are at work here and their current performance should be better than their last.
• Coach/Captain Change: The pillar and foundation of any team, is usually the player that shapes the team, if you move or change that foundation, the shape of the team is completely different. Coaches and captains influence gameplay, style and team shape.
• Gameplay and record: Watching and observing the 5-man roster, from the beginning indicates whether the team follows a successful pattern or not.
• Strength of opposition: A less significant but quite unavoidable parameter, the strength of enemy teams and rivals.

A Real Post-TI Case Study

Team Falcons won The International 2025 with a winning streak in the upper bracket after being a full roster for almost 2 full years. While other teams were shuffling and replacing players, Falcons kept the same roster after TI 2025 and entered the Blast Slam IV stage like kings about to win another tournament. 

Team Tundra, who finished 7^th-8^th place, had shuffled their roster a bit and changed their pos 4 and carry players. Little did anyone expect that such a poorly performing roster at TI would stand any chance of coming close to a championship. 

Tundra and Falcons actually finished the BLAST Slam IV group stage with identical 9-2 records, earning direct semifinal spots. Falcons then defeated HEROIC 2-0, while Tundra beat MOUZ 2-1, setting up a Grand Final between the two group-stage leaders. Tundra eventually defeated the month-old TI champions 3-2, becoming the first team to win three consecutive BLAST Slam events.

This not only shows the power of a newly formed team, but also shows that even unbeatable giants can fall with the right combination of players.

Conclusion — Ratings Need Time to Catch Up

If there was a reset button in the world of Dota 2, it would be The International and the post TI shuffles. This period marks the change of the entire scene and greatly separates between historical team strength and present team strength. 

While rankings remain useful, it is important to understand that the water is still murky and the ratings need time to adjust and provide better description of the current teams and their performances. 

Now is the time for surprises and uncertainty, and a great time for underdogs and completely new teams to take action and prove their worth on the Dota 2 stage.

FAQ

1. Why do post-TI roster shuffles affect Dota 2 team ratings?

Because historical ratings were generated by the previous five-player roster. Changes in players, roles, captains or coaches can make those results less representative of the current team.

2. Does changing one Dota 2 player make a major difference?

It can. A player may contribute drafting, shot-calling, lane synergy and communication in addition to individual mechanical skill.

3. Should bettors ignore historical results after a roster change?

No. Historical results remain useful context, but matches played by the new five-player lineup should carry more weight.

4. Can roster continuity give an underdog an advantage?

Yes. An individually weaker roster that already has established communication and synergy can potentially outperform a newly assembled team of stronger individual players.

5. What should bettors examine after The International?

Roster continuity, positional changes, captain and coach changes, recent drafts, performance with the new five-player lineup and strength of opposition.

6. Where can Dota 2 bettors follow match odds?

Platforms such as Dexsport can provide current Dota 2 betting odds, which bettors can then compare against roster and recent-performance information.
