理由
Irelia is heavily wave-dependent: with dash resets, she can reach you, stick, and force extended fights. With a thin wave, her access drops and your kit is easier to execute.
レーン戦への影響
In lane, mindless pushing gives her minions to dash through and punish you. Midgame, she can force defensive ults, costing your key teamfight tool. In practice it impacts wave priority, reset timing, and river/objective access. A single tempo mistake can lose initiative for the next sequence.
立ち回り方
Control the wave: don’t give her a thick wave near you when W is down. Keep trades short when her wave is strong, longer when it’s thin. In fights, your R can remove her when she dives backline—just ensure your team survives the remaining fight.
