[GAMEPLAY] Syndra's Scatter the Weak Possible bug

I think with Syndra's Scatter the Weak now being changed in the new patch 5.1, you made the stun too strict to land. When I place a Dark Sphere directly onto a champion or minion, the stun now no longer lands and they are just pushed back. I think this is a problem unless this was meant to occur where the Dark Sphere does not cause the stun if directly on the target?
