I thought about that initially. As it turns out, almost every champion in the game has some way of disabling her ulti. Remember that once she takes damage it is disabled and goes on cooldown. Ryze, Teemo, Kayle, Zilean, and Evelynn are the only champs I can think of who can't reliably disable her ult, assuming they properly predict where she is. Her projectiles are visible still, and she leaves a trail after she attacks to make her more visible.
