bait her stun out and juke with your E.
After 6, and she has stun loaded you KNOW she is going to go R Q W E combo.
You just know it.
So once she has that stun loaded, approach her, and the moment u get within her R ranged, you E E right on top of her. Hopefully behind her.
Activate W then Q through her, and poke her a couple times til u have to back out. U can escape through minions if you must. She will choke on her minions.
With her cd's she will only be able to land her W and Q on you. maybe 2 Q's, but with your W passive u will dot her enough, that a simple poke is enough to win the exchange and put her R on cd.
