理由
Sylas can be favorable if you play around his entries: he must go in, so you burn him. Shield blunts part of his burst and you win through constant DPS. Key is denying his preferred extended swing.
レーン戦への影響
He looks for cooldown all-ins; if you hold shield, you can survive. Midgame he can steal ults, but yours is mainly a zone—you control terrain. 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
Hold shield for his engage, not push. Poke then back off, forcing him to enter your zone to trade. At objectives, ult to separate him from resets. Recommended plan: shorter trades, confirm key cooldowns before committing, then convert into prio/vision instead of forcing low-odds all-ins.
