Shyvanna/knockback/Kalista/lee

O.k so I was Dragon decenting on a Kalista, and things just went terribly wrong for me, I caught her During her Walk back animation, though I pushed her the full duration, it didn't seem like she was being knocked back so much as gliding out of the contact zone and did not seem to take damage.

Shyvanna/lee, though it's Impressive that a Well Timed Lee ult can Kick my Decent back mid decent, I kind of can't help but have a wtf moment to the Physics, and be a little bit bitter that He not only takes damage/negate my ult/knock me back out of any kind of range.
