Expert take
Zed is an excellent test of discipline. He rewards players who can read cooldowns, vision, angles, and wave tempo, but quickly exposes those who only see the combo. His real strength is not killing a carry once; it is making the entire enemy team play as if that kill could happen on every rotation. Pick Zed when you can control map rhythm, threaten side lanes, and convert your windows into objectives. Avoid him when your team needs a stable mid who brings crowd control, zone control, or lasting front-to-back presence.
