Dat Hit box on Syndras E

Okay this has been an issue I have had for awhile now and I just want clarification or a fix. when Syndra casts her E "scatter the weak" And one of her spheres are in the E itself more times then I can count the ball wont even be remotely close to me, yet I'll still stunned? It's really frustrating to lane Vs a syndra knowing that even if i dodge her sphere when she E's me there's a good chance I'll still get stunned? I wanted to know if this is how the skill is actually supposed to work or if it is just something that hasn't been noticed yet? Don't get me wrong, I don't think syndra is OP in the slightest but is that really how her stun works?
