How's this for a LeBlanc Nerf?

Make W's AoE smaller.

Distortion should be a mobility spell first, and everything else second. If it hits a smaller area, it can't be used to destroy minion waves easily when LeBlanc is pushed into turret. If she has more difficulty farming under turret, waveclear champs like and suddenly are viable counters to her.

Rather than nerf the fun stuff, like blinking all over the place, nerf the stuff that really shouldn't be there in the first place.
