理由
Kassadin is hard in a structural way: you’re a control mage that wins by enforcing distance, and he’s built to survive AP and eventually break distance as the game progresses. Even if you poke early, if he gets through the first levels without disaster, he plays in your dead zone: close range, resets, where your kit loses cleanliness.
レーン戦への影響
In lane, you may have priority, but you must convert that prio into something (plates, vision, roams) because simply “holding” him doesn’t stop scaling. After his level 5/6 spike, the matchup flips: he forces you back, threatens side lanes, and you can’t safely punish by following.
立ち回り方
Your plan is aggressive but smart: push cleanly, take ward timings, and impact the map before he becomes too mobile. Key timing: pre-spike, you want a real lead (objective, side kill, plates). Concrete decision: after his spike, play more for teamfight setup than duels; use the ball to protect carries/zone and don’t chase Kassadin into fog.
