A Question, in regard to Syndra Stun and Combos.

So, not being a thousand percent familiar with every interaction in the game, I may or may not have fed a Syndra three kills as a jungler, because I misunderstood how her kit actually works. What I THOUGHT happens, was that when she pushes the ball, it was the ball in motion that caused the stun. I thought that the ball had to be down then pushed for the stun to take effect. Her tooltip literally says, "Enemies HIT by Dark Spheres are stunned." What happened to me, was that she would throw a ball down, I would gap close past it, but then she would shove me and the ball away from her, and this would proc her stun. I guess it registered as a hit despite me being on the close side of the ball, even though I wasn't hit by it as we traveled. I'm also saw her e and then throw the ball, which still proc a stun, which I thought was weird, but then after some very quick research (youtube) I saw that this is actually a trick for persons who want to learn Syndra. Like this has been a thing for at least 2 years. I dunno, just seems weird to me. I guess the question(s) I have would be, A) What would be the best way to gank a Syndra as a Graves, B) Does anyone else think that the problem I've describe is pretty B.S., as well?
