T1's lane swap in game 2 was executed perfectly โ the timing of Faker's roam was completely unpredictable.
Standard lane swaps happen after the first gank gets answered. T1 triggered this at minute four โ jungle was just finishing the bottom half of the map, zero vision on the rotation. The immediate lane pressure after the swap led directly into the snowball.
Not luck. Peak game sense. CS differential went from -12 to +28 after that single decision. One call changed the entire meta of the game.
