Why can a 18/14 caitlyn oneshot a Nidalee who got rooted?

Cait has high damage and is kinda fed, and you got rooted as a squishy champion. Why do you think you got one-shot?

I feel like you're getting stuck on the 14 deaths, but 18 kills is 18 kills. You don't lose gold for dying or anything. If she was 18/0 you wouldn't be asking that question is all Im saying.

Must've been near full build consider its 18 kills, and Nidalee isn't at all tanky.
