A slower effect would probably feel worse for opponents - delayed crowd control is so much more frustrating than instant crowd control, especially if there's no "real" way to play against it except leaving. Also, the storm really shouldn't be an effect that zones the enemy players out of an area - that doesn't really benefit Lissandra. It'll end up just getting used to push a turret - since enemies can't afford to stay inside. Ideally, it should be an area that empowers Lissandra without putting an extreme burden on the enemy.
