The QofL change to her passive made it necessary to attack move to properly use her passive later in the game, otherwise 2/3 times the leap doesn't occur, and you just run through the aa animation with no movement. Do you intend to fix this in the next patch?
I thought I just suddenly sucked at her.... LOL
Riot knows this and is working on a fix
I actually JUST played 
Kalista today and I indeed saw this. and found my self asking "Why isn't my jump going off??"
I can kite this blitzcrank

So that's why the game felt inexplicably laggy that one time I played Kalista recently. That's actually a bit relieving.
Ya i been playing kalista a ton and its really annoying.
