Nidalee Unique W Tweak Idea

I was thinking about ways to change Nidalee to make her a little more viable or fun. So the idea is that instead of her trap just applying a small Damage over Time effect it applies a debuff that does damage based on movement. It makes sense for a trap that clamps on your leg to hurt more the more you try to walk with it (like the Ruptured Tendons spell in Divinity Original Sin 2). So that way if you stand still or only move a little bit you will take almost no damage but make yourself more vulnerable to getting hit by a Nid spear and it's a choice you have to make on which damage you would rather take. It's also sort of a small counter to champs that move a lot (Hecarim, Master Yi, etc) because they will take a lot of damage if they keep moving.
