Her E is the last thing that needs a nerf... seriously... it's very easy to dodge. Not only is the animation glaringly obvious, but it's a slow projectile, and you have to stay close to your target to root them (which can be very dangerous). Her annoying Q / R / W (or Q W R if you need the mobility) combo is what needs to be fixed. She's basically ungankable in lane on top of sporting crazy burst damage. Even if you DO have some way of dealing with her W / R escape (and transport back if she feels like juking), and dodge the E, you still have to deal with her passive.
