What are some abilities or nodes that are easy to miss that can completely shut a champion down, or at least a significant part of their kit?
I often forget about champs with Coldsnap or anti-evade as a basic ability that mean you cannot reliably Quake them.
I also got caught a couple of times not realising in story quest that the "ability accuracy + 100%" node effectively shuts Wiccan's Neutralise ability down entirely
