kt Rolster vs Team Vitality: Jarvan IV Tests the Draft Edge

TL;DR: For DCGI Game 2, the model gives kt Rolster 45% and Team Vitality 55%, despite KT’s strong Renekton–Viktor–Ezreal pairings. Vitality’s most notable draft wrinkle is Lee Sin: his 54.7% global WR is strong, but the matchup data puts him at 44.2% against Jarvan IV.

Compositions: kt Rolster vs Team Vitality

kt Rolster’s Renekton, Jarvan IV, Viktor, Ezreal, and Seraphine form a teamfight composition with reliable engage and tools to follow up. Cuzz can start fights with Jarvan IV, while Seraphine adds sustain and Viktor punishes opponents who commit into a tight area. Ezreal gives KT poke and safer damage before a full engage; Renekton can create early pressure and help KT contest the mid-game. In the late game, Viktor and Seraphine offer scaling, but the composition wants to avoid letting Vitality freely control the range of engagements.

Team Vitality has more pick threat and skirmish potential through Ambessa and Lee Sin, with Syndra adding burst and Alistar providing dependable engage. Ziggs can poke and clear waves, helping Vitality siege or stall when direct fights look unfavorable. The composition’s early-to-mid-game route is to use Lee Sin and Alistar to create openings, then let Syndra and Ziggs deal damage from range. Vitality must manage KT’s counter-engage and avoid giving Viktor a clean, extended fight.

Key Picks and Stats

In top lane, KTPerfecT’s Renekton has a 50.5% global WR over 952G; his matchup WR against Ambessa is 56.3% over 71G. VITNaakNako’s Ambessa has a 48.9% global WR over 1370G and a 43.7% WR against Renekton over 71G. That head-to-head favors KT, though the model’s 16-game matchup sample also favors Renekton, at 57.29%.

In the jungle, KTCuzz’s Jarvan IV has a 50.5% global WR over 1657G, compared with VITLyncas’s Lee Sin at 54.7% over 931G. Lee Sin’s global number is a clear strength, but his listed WR against Jarvan IV is 44.2% over 190G, while Jarvan IV is at 44.2% against Lee Sin in the supplied global matchup data—making this a volatile matchup rather than a clean edge.

Mid is close: KTBdd’s Viktor has a 50.3% global WR over 938G and 50.0% against Syndra over 100G. VITFIESTA’s Syndra has a 49.4% global WR over 897G and 50.0% against Viktor over 100G. Bot lane is more complicated for KT: KTJiwoo’s Ezreal is at 50.4% over 1677G, but 44.4% against Ziggs over 45G; VITCarzzy’s Ziggs has a 45.5% global WR over 367G and 55.6% against Ezreal over 45G. Support tilts the other way: KTEffort’s Seraphine has a 54.5% global WR over 987G and 63.2% against Alistar over 19G, while VITFleshy’s Alistar is at 54.7% over 816G.

The forecasted B1 candidates, Cassiopeia and Kalista, did not appear. The pre-draft ban expectations cannot be confirmed from the supplied draft, which lists picks only. Lee Sin is the most striking departure from the forecast: the preview highlighted likely first-pick options, while Vitality instead built around Lee Sin and a direct engage package.

Draft Edge

The model slightly favors Vitality, but KT has the cleaner evidence in key counter-matchups: Renekton into Ambessa and Seraphine into Alistar. Vitality’s advantages are Lee Sin’s strong global WR, Ziggs’s favorable listed matchup into Ezreal, and stronger team form. KT’s win condition is to use Jarvan IV and Seraphine to force fights on its terms, then let Viktor scale; Vitality wants to create early skirmishes and use Ziggs to keep KT from engaging cleanly.

Polymarket Market

Polymarket gives KT 72% to win Game 2 and 68% to win the series now. Before the match, the series market had KT at 88%. That is a 20.0-percentage-point fall for KT, with the market moving toward Vitality. The Game 2 price is 4 percentage points more favorable to KT than the current series price, so bettors see KT as more likely to win this map than the series overall. That confidence runs against the model’s 45%–55% call and may reflect the market’s pre-match view of KT or beliefs about the broader series; the draft itself gives Vitality reasons for optimism, particularly through form and the Ezreal–Ziggs matchup.

Prediction

The draft model’s call is Team Vitality 55%, kt Rolster 45%. I would keep that split rather than shift it: KT’s favorable Renekton and Seraphine matchups are meaningful, but Vitality’s 0.600 team-form signal versus KT’s 0.400 supports the narrow edge. If KT can force coordinated fights before Ziggs controls the map, the game can swing; otherwise Vitality’s ranged pressure and skirmish tools suit the draft.
